IB/qib: Fix memory leak of recv context when driver fails to initialize.
In qib_create_ctxts() we allocate an array to hold recv contexts. Then attempt
to create data for those recv contexts. If that call to qib_create_ctxtdata()
fails then an error is returned but the previously allocated memory is not
freed.
