slimbus: fix retries comparison to correctly identify failed allocation
Currently the check for too many retries fails because retries is actually
-1 when the retry loop terminates if no pbuf can be allocated because of
the post decrement on retries. Fix this by not comparing retries with zero
but instead check if it is negative.
