Hyunwoo Kim 70faf9d9b6 fbdev: smscufx: Fix several use-after-free bugs 
commit cc67482c9e5f2c80d62f623bcc347c29f9f648e1 upstream.

Several types of UAFs can occur when physically removing a USB device.

Adds ufx_ops_destroy() function to .fb_destroy of fb_ops, and
in this function, there is kref_put() that finally calls ufx_free().

This fix prevents multiple UAFs.
