usb: misc: usbtest: format max packet size for iso transfer

Browse Source 
The current code prints all wMaxPacketSize content at endpoint
descriptor, if there is a high speed, high bandwidth endpoint,
it may confuse the users, eg, if there are 3 transactions during
microframe, it will print "wMaxPacket 1400" for packet content.
This commit splits wMaxpacketSize and transaction numbers for
output messages.
