usb: isp1760: remove redundant max_packet() macro 



The function usb_endpoint_maxp() (called by usb_maxpacket()) already
does the sanitazation of the USB endpoint max packet size. The call to
max_packet() does the same thing and is thus removed.

The macro max_packet() not being used anymore also gets removed.
