Subject: [PATCH 5.4 193/261] ima: Remove redundant policy rule set in add_rules()

From: Krzysztof Struczynski <krzysztof.struczynski@...wei.com>

[ Upstream commit 6ee28442a465ab4c4be45e3b15015af24b1ba906 ]

Function ima_appraise_flag() returns the flag to be set in
temp_ima_appraise depending on the hook identifier passed as an argument.
It is not necessary to set the flag again for the POLICY_CHECK hook.
