xfs: don't use xfs_trans_reserve in xfs_trans_reserve_more
xfs_trans_reserve_more just tries to allocate additional blocks and/or rtextents and is otherwise unrelated to the transaction reservation logic. Open code the block and rtextent reservation in xfs_trans_reserve_more to prepare for simplifying xfs_trans_reserve. Signed-off-by: Christoph Hellwig <[email protected]> Reviewed-by: Darrick J.
