Fix usage of wait_io_or_timeout from TLS layers

Browse Source 
wait_io_or_timeout() accepts milliseconds, while options has seconds,
since this is just plain MYSQL_OPT_READ_TIMEOUT/...

The one that has milliseconds are pvio->timeout[PVIO_*_TIMEOUT], so use
them.

Usually this is not a problem, but, in case of interrupt (i.e. signal -
EINTR) SSL_read() will return SSL_ERROR_WANT_READ/SSL_ERROR_WANT_WRITE,
and then wait_io_or_timeout() will be called, and timeout will be wrong,
may cause a failure.
