[PATCH][next] dm ima: Fix resource leaks on error return path

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently there is an error check on r that immediately returns
on an error rather than taking the error clean-up exit path via
label 'error'. Fix this to avoid resource leaks.

Addresses-Coverity: ("Resourced leak")
Fixes: 0a3bec81a409 ("dm ima: measure data on table load")
