[PATCH 5.15.y 3/4] audit: use 'unsigned int' instead of 'unsigned'

[Sasha Levin <sashal@kernel.org>]

From: Ricardo Robaina <rrobaina@redhat.com>

[ Upstream commit 8b226771014beab1292081151a99530886ce54b4 ]

Address checkpatch.pl warning below, across the audit subsystem:

  WARNING: Prefer 'unsigned int' to bare use of 'unsigned'

Minor cleanup, no functional changes.
