[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. Reported-by: Pico Mitchell <pico@randomapplications.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>
