IB/uverbs: reject invalid or unknown opcodes

Browse source

commit b632ffa7ce upstream.

We have many WR opcodes that are only supported in kernel space
and/or require optional information to be copied into the WR
structure.  Reject all those not explicitly handled so that we
can't pass invalid information to drivers.
