drm/amd/display: Remove redundant NULL check in dcn10_set_input_transfer_func
This commit removes an unnecessary NULL check in the
`dcn10_set_input_transfer_func` function in the `dcn10_hwseq.c` file.
The variable `tf` is assigned the address of
`plane_state->in_transfer_func` unconditionally, so it can never be
`NULL`. Therefore, the check `if (tf == NULL)` is unnecessary and has
been removed.
Fixes the below smatch warning:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn10/dcn10_hwseq.c:1839 dcn10_set_input_transfer_func() warn: address of 'plane_state->in_transfer_func' is non-NULL
Fixes: 285a7054bf81 ("drm/amd/display: Remove plane and stream pointers from dc scratch")
