Subject: [PATCH] iwlwifi: don't dump_stack() when we get an unexpected interrupt
Git-commit: 91ca9c3ade1be665f5ce88594ee687c56b0357d5
Patch-mainline: v5.18-rc1
References: bsc#1202131

It is yet unclear if the WARNING really points to a real problem,
but for sure the stack dump doesn't help fixing it.
Just use a regular error print instead.
