anysee: initialize anysee_usb_mutex statically
From: Akinobu Mita <akinobu.mita@gmail.com>
anysee_usb_mutex is initialized at every time the anysee device is probed.
If the second anysee device is probed while anysee_usb_mutex is locked by
the first anysee device, the mutex is broken.
This patch fixes by initialize anysee_usb_mutex statically rather
than initialize at probe time.
