[patch] crypto: qat - fix some timeout tests

[Dan Carpenter <dan.carpenter@oracle.com>]

We do an "if (!times)" test later to see if we ran the loop too many
times, but because it is a postop negate that means times is -1 when we
exit that way.  I have fixed this by changing it from a post op to a
preop.

This means we only loop 9999 times instead of 10000 like before but I
figure it probably doesn't matter.
