bpf: Fix number of retries when growing log buffer
The log buffer is automatically grown when the verifier output does not
fit into the default buffer size. The number of growing attempts was
not sufficient to reach the maximum buffer size so far.
Perform 9 iterations to reach max and let the 10th one fail.
