[PATCH 5.8 296/633] iwlwifi: dbg: run init_cfg function once per driver load

[Greg Kroah-Hartman]

From: Mordechay Goodstein <mordechay.goodstein@xxxxxxxxx>

[ Upstream commit 42f8a2735cc218b6b372134684d4cd3c1423f123 ]

Every time we call init_cfg driver appends the enabled triggers
to the active triggers while this should be done only once per
driver load.
