[PATCH 2/3] ALSA: ens1370: Use common error handling code in snd_audiopci_probe()

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

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 14 Nov 2017 18:15:36 +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.
