RDMA/uverbs: Restrict usage of privileged QKEYs
According to the IB specification rel-1.6, section 3.5.3:
"QKEYs with the most significant bit set are considered controlled
QKEYs, and a HCA does not allow a consumer to arbitrarily specify a
controlled QKEY."
Thus, block non-privileged users from setting such a QKEY.
