media: flexcop-usb: fix NULL-ptr deref in flexcop_usb_transfer_init()
[ Upstream commit 649cd16c438f51d4cd777e71ca1f47f6e0c5e65d ]
If usb_set_interface() failed, iface->cur_altsetting will
not be assigned and it will be used in flexcop_usb_transfer_init()
It may lead a NULL pointer dereference.
Check usb_set_interface() return value in flexcop_usb_init()
and return failed to avoid using this NULL pointer.
