Bob Ham e4a886e811 hwrng: chaoskey - Fix URB warning due to timeout on Alea 
The first read on an Alea takes about 1.8 seconds, more than the
timeout value waiting for the read.  As a consequence, later URB reuse
causes the warning given below.  To avoid this, we increase the wait
time for the first read on the Alea.
