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

Browse Source 
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
