xfs: pass back updated nb from xfs_growfs_compute_deltas

xfs_growfs_compute_deltas can update nb for corner cases like a number
of blocks that would create a less the minimal sized AG, or running
past the max AG limit.  Pass back the calculated value to the caller,
as it relies on to calculate the new number of perag structures.

Note that the grown file system size is not affected by this
miscalculation as it uses the passed back delta value.
