FASTBOOT: Download performance tuning

Increase bulk packet size from 512 to 1024, which helps download
throughput on Linux.  For some reason my MacbookPro gives slower
download throughput.

Also eliminate one level of memcpy by changing the rcv_urb buffer
to point directly to our transfer buffer during a download.
