drm/amd/display: Fix index out of bounds in DCN30 color transformation
This commit addresses a potential index out of bounds issue in the
`cm3_helper_translate_curve_to_hw_format` function in the DCN30 color
management module. 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.
