------------------------------------------------------
Subject: ecryptfs: fix premature release of file_info memory
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
The file_info struct is being released, and then one of its members is
referenced from the released memory. This patch cleans up the function and
moves the release so that it occurs after the reference.
