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

In the Linux kernel, the following vulnerability has been resolved:

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 (TRANSFER_FUNC_POINTS).

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.
