rv: Fix missing unlock on double nested monitors return path

Browse source

RV doesn't support nested monitors having children monitors themselves
and exits with the EINVAL code. However, it returns without unlocking
the rv_interface_lock.

Unlock the lock before returning from the initialisation function.
