net: clear sk_err_soft in sk_clone_lock()
commit e551c32d57c88923f99f8f010e89ca7ed0735e83 upstream.
At accept() time, it is possible the parent has a non zero
sk_err_soft, leftover from a prior error.
Make sure we do not leave this value in the child, as it
makes future getsockopt(SO_ERROR) calls quite unreliable.
