Subject: [PATCH RFC] qla2xxx: fix timeout in qla2x00_down_timeout
iterations is unsigned, so it is impossible to get out of the loop
and return -ETIMEDOUT.
Signed-off-by: Bill Nottingham <notting@...hat.com>

If the intention *is* to never fall out of the end of the loop, ignore
this, and just replace it with do {} while (1);.
