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().
