macfb: fix overflow of color_palette array
The palette_current index counter has a maximum size of 256 * 3 to cover a full color palette of 256 RGB entries. Linux assumes that the palette_current index wraps back around to zero after writing 256 RGB entries so ensure that palette_current is reset at this point to prevent data corruption within MacfbState.
