xfs: fix 32-bit truncation in xfs_compute_rextslog
It's quite reasonable that some customer somewhere will want to
configure a realtime volume with more than 2^32 extents. If they try to
do this, the highbit32() call will truncate the upper bits of the
xfs_rtbxlen_t and produce the wrong value for rextslog. This in turn
causes the rsumlevels to be wrong, which results in a realtime summary
file that is the wrong length. Fix that.
