Subject: [PATCH] ice: Don't use GFP_KERNEL in atomic context

ice_misc_intr() is an irq handler. It should not sleep.

Use GFP_ATOMIC instead of GFP_KERNEL when allocating some memory.

Fixes: 348048e724a0 ("ice: Implement iidc operations")

I've never played a lot with irq handler. My understanding is that they should never
sleep. So GFP_KERNEL must be avoided. So I guess that this patch is correct.

However, I don't know if some special cases allow such allocation.
Any feedback/pointer to a good doc/explanation is welcome :)
