This commit removes all the remaining Debugger() calls and KKASSERTs in the
I/O error path. Errors are now propagated up the call tree and properly
reported.
* Report I/O errors instead of asserting.
* Read or Write errors in the flush path disable flushing and force the mount
into read-only mode. Modified buffers are left locked in memory until
umount to provide a consistent snapshot of the state of the filesystem.
You must umount and remount to recover the filesystem. The filesystem
will automatically rollback to the last valid flush upon remounting.
* umount and umount -f are now able to unmount a HAMMER filesystem that has
catastrophic write errors (e.g. pulling the USB cable on an external
drive).

When dealing with a failed read properly set B_INVAL.

Fix multiple bugs in CAM related devices which go away unexpectedly. This
fixes numerous panics when pulling a USB mass media device in the midst of
heavy I/O.
* The SIM lock was being unlocked via the periph->sim path after periph
was unheld. periph can become free and blow up the unlock, so get
the sim into a local variable first, then release periph.
* The code which waits for CCB completion needs to be a while loop, not
an if. It worked anyway, but wasn't very robust.
* Add CAM_SIM_DEREGISTERED to flag when a sim is undergoing deregistration.
* Beef up cam_dead_sim so it works more like a real sim.
* Properly install &cam_dead_sim in the device and periph structures
related to a SCSI bus, when deregistering the bus.
* Disallow the addition of new devices when deregistering a bus.
* NULL out periph->softc when freeing it.

Make some adjustments to the buffer cache:
* Retain B_ERROR instead of clearing it.
* Change B_ERROR's behavior. It no longer causes the buffer to be
invalidated on write.
* Change B_NOCACHE's behavior. It no longer causes the buffer to be
invalidated while the buffer is marked dirty.
* Code that was supposed to re-dirty a failed write buffer in brelse()
was not running because biodone() cleared the fields brelse() was
testing. Move the code to biodone().
* When attempting to reflush B_DELWRI|B_ERROR'd buffers, sleep a tick
to try to avoid a live-lock.
