drm/amd/display: Remove redundant non-zero and overflow check
[Why]
Unsigned int is guaranteed to be >= 0, and read_channel_reply checks for
overflows. read_channel_reply also returns -1 on error, which is what
dc_link_aux_transfer is expected to return on error.
[How]
Remove the if-statement. Return result of read_channel_reply directly.
