drm/amd/display: fix dp_retrieve_lttpr_cap() return value

Browse Source 
gcc-13 notices a mismatch between the return type of dp_retrieve_lttpr_cap()
and the returned value:

drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dp_capability.c: In function 'dp_retrieve_lttpr_cap':
drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dp_capability.c:1465:24: error: implicit conversion from 'enum <anonymous>' to 'enum dc_status' [-Werror=enum-conversion]
 1465 |                 return false;
      |                        ^~~~~

Change the value to an actual dc_status code and remove the bogus
initialization that was apparently meant to get returned here.
