Subject: ionic: fix a sleeping in atomic bug
Patch-mainline: v5.15-rc1
Git-commit: 52a67fbf0cffcc1a0d1272cf0522cb193a0d0bd6
References: jsc#SLE-19282
This code is holding spin_lock_bh(&lif->rx_filters.lock); so the
allocation needs to be atomic.
Fixes: 969f84394604 ("ionic: sync the filters in the work task")
