IB/srp: Enforce protocol limit on srp_sg_tablesize
The current SRP initiator will allow unlimited s/g entries in the
indirect descriptors lists, but the entry count field in the SRP_CMD
request is 8 bits, so setting srp_sg_tablesize too large will open the
possibility of wrapping the count and generating invalid requests.
Clamp srp_sg_tablesize to the protocol limits to prevent surprises.
