crypto: omap-aes - Drop if with an always false condition

The remove callback is only called after probe completed successfully.
In this case platform_set_drvdata() was called with a non-NULL argument
and so dd is never NULL.

This is a preparation for making platform remove callbacks return void.

While touching this driver remove a stray empty line.
