[PATCH 2/2] xen-tpmfront: Combine two condition checks into one statement in vtpm_send()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 22 Oct 2017 13:15:16 +0200

A return was performed with the same error code after two condition checks.
Thus use a single statement instead.
