Subject: [PATCH 06/29] IB/mlx4: Delete three unnecessary return statements

From: Markus Elfring <elfring@...rs.sourceforge.net>

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such a statement in the affected functions.
