target/file: Remove fd_prot bounce buffer
The reason this bounce buffer exists is to allow code reuse between rd_mcp and fileio in DIF mode. But the fact is, that this bounce is really not needed at all, we can simply call sbc_dif_verify on cmd->t_prot_sg and use it for file IO. This also removes fd_do_prot_rw as fd_do_rw was generalised to receive file pointer, block size (8 bytes for DIF data) and total data length. (Fix apply breakage from commit c836777 - nab) Tested-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
