Subject: [PATCH vfio 2/2] vfio/mlx5: Destroy the state_mutex on release

The state_mutex is initialized in vfio init, but
never destroyed. This isn't required as mutex_destroy()
doesn't do anything unless lock debugging is enabled.
However, for completeness, fix it.

No fixes tag is added as it doesn't seem worthwhile
for such a trivial and debug only change.
