jack: initialize audioOutput->data

Browse Source 
Initialize audioOutput->data with NULL in jack_initDriver().
Previously, this was never initialized, although the other functions
relied on it being NULL prior to jack_openDevice().

This patch addresses bug 0001641[1].  In contrast to the patch provided
by the bug reporter, it moves the initialization before the "!param"
check.
