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

[Christophe JAILLET]

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

Use GFP_ATOMIC instead of GFP_KERNEL when allocating some memory.

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 :)
