[rdma-core patch v2] srp_daemon: print maximum initiator to target IU size

[Honggang LI]

From: Honggang Li <honli@redhat.com>

The 'Send Message Size' field of IOControllerProfile attributes
contains the maximum initiator to target IU size.

When there is something wrong with SRP login to a third party
SRP target, whose ib_srpt parameters can't be collected with
ordinary method, dump the 'Send Message Size' may help us to
diagnose the problem.

Applied, thanks

Things will go faster if you send rdma-core patches as PRs.. It saves
me a bunch of work :)
