ALSA: line6: Fix NULL dereference at podhd_disconnect()
When podhd_init() failed with the acquiring a ctrl i/f, the line6
helper still calls the disconnect callback that eventually calls again
usb_driver_release_interface() with the NULL intf.
Put the proper NULL check before calling it for avoiding an Oops.
Fixes: fc90172ba283 ("ALSA: line6: Claim pod x3 usb data interface")
