[PATCH] fs: jffs2: silence false positive by always initializing variable

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

buffer is not initialized when pointed is true, but that can't
happen, because, unlike Linux, we hardcode the value at 0.

clang warns about that though, so fix the warning by always
initializing buffer.
