Mike Marciniszyn 13bac86195 IB/hfi1: Fix abba locking issue with sc_disable() 
sc_disable() after having disabled the send context wakes up any waiters
by calling hfi1_qp_wakeup() while holding the waitlock for the sc.

This is contrary to the model for all other calls to hfi1_qp_wakeup()
where the waitlock is dropped and a local is used to drive calls to
hfi1_qp_wakeup().

Fix by moving the sc->piowait into a local list and driving the wakeup
calls from the list.

Fixes: 099a884ba4 ("IB/hfi1: Handle wakeup of orphaned QPs for pio")
