media: rockchip/rga: do proper error checking in probe 

[ Upstream commit 6150f276073a1480030242a7e006a89e161d6cd6 ]

The latest fix for probe error handling contained a typo that causes
probing to fail with the following message:

  rockchip-rga: probe of ff680000.rga failed with error -12

This patch fixes the typo.
