Subject: [PATCH] net: ena: ethtool: remove redundant non-zero check on rc

From: Colin Ian King <redacted>

The non-zero check on rc is redundant as a previous non-zero check on rc will
always return and the second check is never reached, hence it is redundant
and can be removed.  Also remove a blank line.
