xfs: fix bounds check in xfs_defer_agfl_block()
Source kernel commit: 1f23d5cb44904e4f51d796578a9b85cf7f10c5dc
Need to happen before we allocate and then leak the xefi. Found by
coverity via an xfsprogs libxfs scan.
[djwong: This also fixes the type of the @agbno argument.]
Fixes: 7dfee17b13e5 ("xfs: validate block number being freed before adding to xefi")
