USB: xhci: use xhci_handle_event instead of handle_event

The former is way to generic for a global symbol.

Fixes this build error:

drivers/usb/built-in.o: In function `.handle_event': (.text+0x67dd0): multiple definition of `.handle_event'
drivers/pcmcia/built-in.o:(.text+0xcfcc): first defined here
drivers/usb/built-in.o: In function `handle_event': (.opd+0x5bc8): multiple definition of `handle_event'
drivers/pcmcia/built-in.o:(.opd+0xed0): first defined here
