media: imx335: Update HBLANK range on mode change

While switching modes, updating to a different value of HBLANK isn't
sufficient, as this is a read-only control with a single allowed value,
and thus hblank_min == hblank_max == hblank of the default mode.

So to correctly update the user-facing value of the HBLANK parameter,
which is necessary for correct framerate calculation, update the whole
range when switching modes.
