USB - Avoid unnecessary reprobes.

* Do not unconditionally setdiskinfo when a removable DA* device is
  opened.  It takes time for the kernel to reprobe the drive and this
  seriously messes up mountroot during kernel boot or attempts to
  access partitions in slices (instant open + access partition).

  If the size hasn't changed, do not call setdiskinfo again.

* This is a bad hack.  A better solution (detect actual device
  replacement) is needed.
