Use 'unsigned int' for indexes, in order to fix the following build warnings
with W=1 option:
drivers/usb/core/usb.c: In function 'usb_find_alt_setting':
drivers/usb/core/usb.c:89:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
drivers/usb/core/usb.c: In function 'usb_altnum_to_altsetting':
drivers/usb/core/usb.c:159:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
