xfs: write the rt super immediately during repair

xrep_rgsuperblock has an unfortunate flaw -- even if the repair
transaction commits and is persisted to disk, a crash before the log
bwrite()s the buffer to disk means that the filesystem will not mount
after recovery.  The xfs_mount keeps the rtsb buffer live for the
duration of the mount (scrubbers hold a file open on the fs) so let's
write the buffer out immediately to shorten that window.
