[efi] Avoid dragging in USB subsystem via efi_usb_path()

Commit 87e39a9c9 ("[efi] Split efi_usb_path() out to a separate
function") unintentionally introduced an undefined symbol reference
from efi_path.o to usb_depth(), causing the USB subsystem to become a
dependency of all EFI builds.

Fix by converting usb_depth() to a static inline function.
