net: wwan: iosm: Call mutex_init before locking it
wwan_register_ops calls wwan_create_default_link, which ends up in the
ipc_wwan_newlink callback that locks ipc_wwan->if_mutex. However, this
mutex is not yet initialized by that point. Fix it by moving mutex_init
above the wwan_register_ops call. This also makes the order of
operations in ipc_wwan_init symmetric to ipc_wwan_deinit.
