xfs: restore old agirotor behavior

Source kernel commit: 127c6534882090d848652a723b436eaef90fce53

Prior to the removal of xfs_ialloc_next_ag, we would increment the agi
rotor and return the *old* value.  atomic_inc_return returns the new
value, which causes mkfs to allocate the root directory in AG 1.  Put
back the old behavior (at least for mkfs) by subtracting 1 here.

Fixes: 20a5eab49d35 ("xfs: convert xfs_ialloc_next_ag() to an atomic")
