octeon_ep: initialize mbox mutexes
The two mbox-related mutexes are destroyed in octep_ctrl_mbox_uninit(),
but the corresponding mutex_init calls were missing.
A "DEBUG_LOCKS_WARN_ON(lock->magic != lock)" warning was emitted with
CONFIG_DEBUG_MUTEXES on.
Initialize the two mutexes in octep_ctrl_mbox_init().
Fixes: 577f0d1b1c5f ("octeon_ep: add separate mailbox command and response queues")
