KVM: selftests: Add KVM_SET_USER_MEMORY_REGION2 helper

Browse source

Add helpers to invoke KVM_SET_USER_MEMORY_REGION2 directly so that tests
can validate of features that are unique to "version 2" of "set user
memory region", e.g. do negative testing on gmem_fd and gmem_offset.

Provide a raw version as well as an assert-success version to reduce
the amount of boilerplate code need for basic usage.
