python: Catch exception "SSL.SysCallError" for send by SSL.

When OVSDB server is aborted, the SSL send function will throw SSL.SysCallError exception, which we need to catch and return it's -errno. While SSL.WantWriteError exception needs to return -EAGAIN based on its parent class, not EAGAIN Signed-off-by: Guoshuai Li <[email protected]> Signed-off-by: Ben Pfaff <[email protected]>
