xfs: fix integer overflow problem when setting large free areas
LOLLM points out that the min_t comparison in xrep_rtbitmap_mark_free
operates on a 64-bit bitmap word offset quantity and a 32-bit
words-per-block ratio. Unfortunately, I should have done the comparison
with the (64-bit) xrep_wordoff_t type, but used the 32-bit word count
type. Oops.
