[PATCH] pcmcia/vrc4171: Use common error handling code in vrc4171_card_init()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Mon, 30 Oct 2017 14:05:35 +0100

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
