The rdma_cm module will later use the P_Key from the BTH to de-mux

I've been hitting errors with srp target with this series applied.
Not sure if this series exposes a bug in ib_srpt or breaks it at
this point, so I just thought I'd send it out at the meantime...
Looks like for some reason cm_get_bth_pkey got pkey_index of 0xffff
instead of 0 (working on the default pkey 0xffff at entry 0).
I have modified the srp initiator, but I doubt that my changes are
related at the moment as well as I didn't modify the channel
establishment at all.
