BUG/MINOR: ssl: fix double-free on failed realloc in ssl_sock.c

Browse Source 
Recent commit 90bfbea7c0 ("BUG/MINOR: ssl: fix memory leaks on realloc
failure in ssl_sock.c") accidentally turned a memory leak in case of
allocation failure into a double-free: the original pointer must no
longer be released. In addition, the allocated_size has to be reset
in case of failure. This needs to be backported to 3.3 like previous
commit.
