drm/amd/display: fix transfer function passed to build_coefficients()
The default argument should be enum TRANSFER_FUNCTION_SRGB rather than
the current boolean value which improperly maps to
TRANSFER_FUNCTION_BT709.
Commit 9b3d76527f6e ("drm/amd/display: Revert adding degamma coefficients")
looks to have improperly reverted
commit d02097095916 ("drm/amd/display: Add regamma/degamma coefficients and set sRGB when TF is BT709")
replacing the enum value with a boolean value.
