[usb] Allow endpoints to be refilled to a specified upper limit

Browse Source 
For USB mass storage devices, we do not want to submit more bulk IN
packets than are required for the inbound data, since this will waste
memory.

Allow an upper limit to be specified on each refill attempt.  The
endpoint will be refilled to the lower of this limit or the limit
specified by usb_refill_init().
