Nicholas Bellinger afd73f1b60 target: Perform PROTECT sanity checks for WRITE_SAME
This patch adds a call to sbc_check_prot() within sbc_setup_write_same()
code to perform the various protection releated sanity checks, including
failing if WRPROTECT or RDPROTECT is set for a backend device that has
not advertised support for T10-PI.

Also, since WRITE_SAME + T10-PI is currently not supported by IBLOCK +
FILEIO backends, go ahead and fail if ->execute_write_same() is invoked
with a non zero cmd->prot_op.
