[PATCH i-g-t 23/37] lib/igt_fb: Fix planar block copy

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The block copy code tries to handle planar formats by blitting
each color plane separately. But it incorrectly picks some of
the parameters (size, bpp, etc.) from the first color plane
instead of the one it's actually copying. Pick the parameters
from the correct color plane.
