Bluetooth: btmtk: Fix btmtk.c undefined reference build error harder

The previous fix was incomplete as the link failure still persists
with CONFIG_USB=m when the sdio or serial wrappers for btmtk.c
are build-in:

btmtk.c:(.text+0x468): undefined reference to `usb_alloc_urb'
btmtk.c:(.text+0x488): undefined reference to `usb_free_urb'
btmtk.c:(.text+0x500): undefined reference to `usb_anchor_urb'
btmtk.c:(.text+0x50a): undefined reference to `usb_submit_urb'
btmtk.c:(.text+0x92c): undefined reference to `usb_control_msg'
btmtk.c:(.text+0xa92): undefined reference to `usb_unanchor_urb'
btmtk.c:(.text+0x11e4): undefined reference to `usb_set_interface'
btmtk.c:(.text+0x120a): undefined reference to `usb_kill_anchored_urbs'

Disallow this configuration.
