libavformat/tls_libtls: handle TLS_WANT_{POLLIN, POLLOUT} in read/write functions
According to the tls documentation: tls_read() and tls_write() can
return TLS_WANT_POLLIN and TLS_WANT_POLLOUT which indicates that the
same operation must be repeated immediately.
This commit prevents the libtls backend from failing when libtls returns
TLS_WANT_POLLIN or TLS_WANT_POLLOUT with the following error:
[tls @ 0x7f6e20005a00] (null)
