[PATCH][next] drm/dp: remove redundant check on ret and return statement

[Colin Ian King]

There is a redundant check on return and a return statement after
a previous return statement from the call to drm_dp_dpcd_write_byte.
These statements are redundant and can be removed. Remove the
statements and the now unused variable ret.
