[PATCH 4/4] staging/wlan-ng/prism2fw: Use common error handling code in writeimage()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 13 Dec 2017 13:41:41 +0100

Replace two calls of the function "kfree" by a jump to the same statements
at the end of this function so that the generated object code could become
a bit smaller.
