xfs: fix incorrect test in xfs_alloc_ag_vextent_lastblock 

When I lifted the code in xfs_alloc_ag_vextent_lastblock out of a loop,
I forgot to convert all the accesses to len to be pointer dereferences.

Coverity-id: 1457918
Fixes: 5113f8ec37 ("xfs: clean up weird while loop in xfs_alloc_ag_vextent_near")
