media: mtk-jpegenc: Fix bug in JPEG encode quality selection

Browse source

The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.

Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.
