Fix uninitialized variable 'option_len' in getsockopt. The parameter option_len is a pointer to an in/out variable. On input, it must specify the size of the output buffer. When uninitialized to a value smaller than the result of getsockopt, the method returns EINVAL.

Sorry for the delay, I somehow missed my email notification on this. I am having somebody who's having a similar problem test your fork.

It looks like it helped that person. Merging this in.

Thanks a lot!
