xfs: remove xfs_alloc_arg firstblock field
The xfs_alloc_arg.firstblock field is used to control the starting agno for an allocation. The structure already carries a pointer to the transaction, which carries the current firstblock value. Remove the field and access ->t_firstblock directly in the allocation code. Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
