Mike Marciniszyn 9aefcabe57 IB/hfi1: Reduce lock contention on iowait_lock for sdma and pio
Commit 4e045572e2 ("IB/hfi1: Add unique txwait_lock for txreq events")
laid the ground work to support per resource waiting locking.

This patch adds that with a lock unique to each sdma engine and pio
sendcontext and makes necessary changes for verbs, PSM, and vnic to use
the new locks.

This is particularly beneficial for smaller messages that will exhaust
resources at a faster rate.
