Log Message:
Pull up following revision(s) (requested by hannken in ticket #758):
        sys/kern/vfs_wapbl.c: revision 1.53
        sys/kern/vfs_wapbl.c: revision 1.54
wapbl_biodone: Release the buffer before reclaiming the log.
   wapbl_flush() may wait for the log to become empty and
   all buffers should be unbusy before it returns.
Try to coalesce writes to the journal in MAXPHYS sized and aligned blocks.
Speeds up wapbl_flush() on raid5 by a factor of 3-4.
Discussed on tech-kern.
Needs pullup to NetBSD-6.
