memif: Validate descriptors within process boudary

We hit a crash when the client sends us a bogus deescriptor which causes us
to access memory beyong the mapping. While the client clearly should not do
that, it is rather cheap for VPP to validate the descriptor instead of crash
and burn.

Type: fix
