usb: dwc3: Fix incorrect PCM value for mult less than 2 



For isochronous endpoints with mult less than 2, the
PCM value of the trb->size is set incorrectly.
For case of mult = 1, this is set to 0/-1 and for
mult = 0, this is set to -2.
This is because the initial mult is set to
ep->mult - 1. Fix this by setting the value of
initial value of mult to 2.
