ALSA: usb-audio: Fix NULL pointer deference in try_to_register_card
[ Upstream commit 28412b489b088fb88dff488305fd4e56bd47f6e4 ]
In try_to_register_card(), the return value of usb_ifnum_to_if() is
passed directly to usb_interface_claimed() without a NULL check, which
will lead to a NULL pointer dereference when creating an invalid
USB audio device. Fix this by adding a check to ensure the interface
pointer is valid before passing it to usb_interface_claimed().
Fixes: 39efc9c8a973 ("ALSA: usb-audio: Fix last interface check for registration")
