[PATCH] libxfont: An uninitialized pointer causes a crash if pcf header is corrupted.

[Olli Vertanen]

If pcfReadTOC() or pcfGetProperties() fail in the beginning
of execution of pcfReadFont(), function tries to free an
uninitialized pointer (isStringProp) when bailing out.

The pointer gets now initialized correctly.
