IB/hfi1: Replace qp->refcount release code with standard driver wrapper

Some parts of the code don't use the standard release
wrapper rvt_put_qp() for decrementing and testing
the refcount to then try to use a resource.
Replace this code with the standard driver wrapper.

Fixes: Commit 4d6f85c3fa55 ("IB/rdmavt, IB/qib, IB/hfi1: Use new QP put get routines")
