Subject: qcam: Fix YUV planar fragment shaders
Commit 251f0534b74b ("qcam: viewfinder_gl: Take color space into account
for YUV rendering") introduced compilation failures in the YUV
semi-planar and planar fragment shaders due to a bad copy & paste. Fix
it.
Fixes: 251f0534b74b ("qcam: viewfinder_gl: Take color space into account for YUV rendering")
