[ Upstream commit dcc14cfd7debe11b825cb077e75d91d2575b4cb8 ]
Both p9_fd_create_tcp() and p9_fd_create_unix() will call p9_socket_open(). If the creation of p9_trans_fd fails, p9_fd_create_tcp() and p9_fd_create_unix() will return an error directly instead of releasing the cscoket, which will result in a socket leak.
This patch adds sock_release() to fix the leak issue.
