target/sbc: Add sbc_dif_read_strip software emulation
Split up __sbc_dif_verify_read() so that VERIFY READ emulation can perform target-core specific READ_STRIP, seperate from the existing FILEIO/RAMDISK backend emulation code. Also add sbc_dif_read_strip() in order to determine number of sectors using cmd->prot_length, and skip the extra sbc_dif_copy_prot(). Reviewed-by: Sagi Grimberg <sagig@mellanox.com> Cc: Martin K.
