[PATCH] thermal: armada: fix incorrect check for drvdata allocation failure

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Currently the drvdata allocation failure is being incorrectly checked by
checking priv and not drvdata.  Fix this and also free priv to fix a
memory leak.

Detected by Coverity Scan, CID#1472102 ("Logically dead code")

Fixes: c9899c183921 ("thermal: armada: use the resource managed registration 
helper alternative")
