Maxime Coquelin 9fce5d0b40 vhost: do not take lock on owner reset 
A deadlock happens when handling VHOST_USER_RESET_OWNER request
for the same reason the lock is not taken for
VHOST_USER_GET_VRING_BASE.

It is safe not to take the lock, as the queues are no more used
by the application when the virtqueues and the device are reset.

Fixes: a368804699 ("vhost: protect active rings from async ring changes")
