[PATCH] drm/amd/display: Improve 'dml32_TruncToValidBPP()' function

[Srinivasan Shanmugam]

Refactors the dml32_TruncToValidBPP function by removing a
redundant return statement.

The function previously had a return statement at the end that was
never executed because all execution paths in the function ended with
a return statement before this line.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:1680 dml32_TruncToValidBPP() warn: ignoring unreachable code.
