IB/iser: Support T10-PI operations
Add logic to initialize protection information entities. Upon each
iSCSI task, we keep the scsi_cmnd in order to query the scsi
protection operations and reference to protection buffers.
Modify iser_fast_reg_mr to receive indication whether it is
registering the data or protection buffers.
In addition introduce iser_reg_sig_mr which performs fast registration
work-request for a signature enabled memory region
(IB_WR_REG_SIG_MR). In this routine we set all the protection
relevants for the device to offload protection data-transfer and
verification.
