xfs: simplify the xfs_rmap_{alloc,free}_extent calling conventions

Source kernel commit: 953f76bf7a3622351f335c77c56ed7efb793e3e7

Simplify the calling conventions by allowing callers to pass a fsbno
(xfs_fsblock_t) directly into these functions, since we're just going to
set it in a struct anyway.
