Subject: [PATCH][next] drm/omap: clean up error exit path on omap_encoder allocation failure

Currently when an allocation failure occurs for omap_encoder the exit
path will destroy encoder via omap_encoder_destroy  if it is not null.
However, encoder is always null at this point, so the check and destroy
is redundant and can be removed. Clean up the code by removing the exit
path and redundant omap_encoder_destroy call, and just return NULL.
