[PATCH 5/5] wlcore: Use common error handling code in wl1271_op_suspend()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 29 Oct 2017 20:36:39 +0100

Add a jump target so that a specific error message is stored only once
at the end of this function implementation.
Replace two calls of the macro "wl1271_warning" by goto statements.

This issue was detected by using the Coccinelle software.
