drm/amd/display: Fix index out of bounds in degamma hardware format translation

Fixes index out of bounds issue in cm_helper_translate_curve_to_degamma_hw_format function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFERFUNCPOINTS).

The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds the function returns false to indicate an error.
