From: Nicholas Bellinger <n...@linux-iscsi.org>
This patch adds READ_INSERT support in target_check_read_prot() that
invokes sbc_dif_generate() when LIO is responsible for generating the
outgoing T10-PI.
Required for supporting fabrics that exchange protection information,
and would like to function with un-protected devices.
