Subject: [PATCH 5/5] usbredirparser: Update header-len inside the
 usbredirparser_do_read loop

If we process the hello packet with the 64 bit id capability bit in the same
loop as other packets (because they were send quickly after one each other),
then we end up reading 48 bytes for the header of the next packets processed
in the same loop, while we should read 64 bytes for them, causing the
sender and receiver to get out of sync.
