USB: gadget: dummy_hcd.c: fix nested switch statements
Fix a messed up combination of two nested switch statements in
drivers/usb/gadget/dummy_hcd.c.
According to the USB spec (section 5.8.3) the maximum packet size for bulk
endpoints can be 512 for high-speed devices and 8, 16, 32 or 64 for full-speed
devices. Low-speed devices must not have bulk endpoints.
