Israel Rukshin 0a475ef422 IB/srp: fix invalid indirect_sg_entries parameter value
After setting indirect_sg_entries module_param to huge value (e.g 500,000),
srp_alloc_req_data() fails to allocate indirect descriptors for the request
ring (kmalloc fails). This commit enforces the maximum value of
indirect_sg_entries to be SG_MAX_SEGMENTS as signified in module param
description.

Fixes: 65e8617fba (scsi: rename SCSI_MAX_{SG, SG_CHAIN}_SEGMENTS)
Fixes: c07d424d61 (IB/srp: add support for indirect tables that don't fit in SRP_CMD)
