usb: ohci-hcd: annotate switch/case fallthrough

The USB OCHI code uses an implicit switch/case fallthrough after checking
for valid descriptor IDs.

Add our "fallthrough;" statement-like macro before the default branch in
the OHCI code, to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.
