Subject: [PATCH][next] crypto: cavium: Fix inverted logic on timeout end check

Currently the timeout check will immediately break out of the
while loop because timeout-- is always true on the first
iteration because timeout was initialized to 100. The check
is inverted, it should exit when timeout is zero. Fix this
by adding the missing ! operator.
