[034/244] savagedb: Fix typo causing regression in savage4 series video chip detection

From: Greg KH

3.0-stable review patch. If anyone has any objections, please let us know.

------------------

From: John Stanley <jpsinthemix@xxxxxxxxxxx>

commit 4b00e4b3940eabb38adeec0823751820fe2d6fda upstream.

Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES
macro was incompletely modified, resulting in a false positive detection
of a savage4 card regardless of which savage card is actually present.

For non-savage4 series cards, such as a Savage/IX-MV card, this results
in garbled video and/or a hard-hang at boot time. Fix this by changing
an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.
