Mark Johnston d76d79fd27 zio: Avoid sleeping in the I/O path
zio_delay_interrupt(), apparently used for fault injection, is executed
in the I/O pipeline.  It can cause the calling thread to go to sleep,
which is not allowed on FreeBSD.  This happens only for small delays,
though, and there's no apparent reason to avoid deferring to a taskqueue
in that case, as it already does otherwise.

Simply go to sleep unconditionally.  This fixes an occasional panic I
see when running the ZTS on FreeBSD.  Also remove an unhelpful comment
referencing the non-existent timeout_generic().
