Subject: [PATCH 2/2] InfiniBand-iSER-target: One jump label less in
 isert_reg_sig_mr()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 27 Dec 2015 12:54:52 +0100

This issue was detected by using the Coccinelle software.

1. Let us return directly if a call of the function "isert_set_sig_attrs"
   or "ib_post_send" failed.

2. Delete the jump label "err" then.

3. Return zero as a constant at the end.
