drm/amd/display: Remove useless assignments
[WHAT & HOW]
"split_pipe" are assigned to test_pipe and then immediately are updated
to other values. The same also applies to "status" as well.
Similarly, "id", "dwb" and "unused_dpps" are assigned but the functions
immediately return, and thus they have no effects.
As a results, the assignments removed.
This fixes 5 UNUSED_VALUE issues reported by Coverity.
