fifos - fix broken mkfifo style fifos.

Allow the flag (it is harmless and does nothing).

bioqdisksort - fixes to avoid starvation
Long chains of pipelined write I/O were being sorted in front of other
requests. Due to the pipelining these other requests would wind up
getting starved virtually permanently.
Prevent starvation by forcing one out of every 16 BIOs to be ordered.
This fixes issues with HAMMER which tends to have more of an absolute
ordering of meta data verses data then UFS.
