USB: f_mtp: Set maximum burst value to two for superspeed mode

Browse source 
Currently burst value is set to zero for superspeed in mtp driver.
MTP throughput can be improved by setting max burst value to non
zero value in superspeed mode. Hence set max burst value to two
for both IN and OUT bulk endpoints in superspeed mode.
