47183f2b16 ib_srpt: Fix a race condition in the initialization code 
Initialize port information before registering the CM ID. One of
the functions called by the CM handler (srpt_cm_req_recv())
namely uses the SCST target pointer so that pointer must be
initialized before the CM ID is registered. This patch avoids that
SRP login during ib_srpt initialization sporadically triggers the
following bug:

ib_srpt: Rejecting login with reason 0x10001
BUG: unable to handle kernel NULL pointer dereference at 0000000000000100

6d9c43f821 ib_srpt: Reduce default value of srpt_sq_size 
Reduce the default value of the srpt_sq_size kernel module
parameter from 4096 to 256. This avoids on recent kernels
(e.g. 4.1.0) QP creation causes swiotlb to complain about a
failed allocation.
