wl1251: wait for join command complete event

Poll for join command completion instead of waiting blindly for 10
msecs. There is a timeout of 100 msecs, if the command doesn't complete
by then, we return an error code.

Based on wl1271 patch 99d84c1de8fdf5f9b09f07fdbc628857a040bf8b
by Luciano Coelho.
