[PATCH V2] hyper-v: use GFP_KERNEL for hv_context.hv_numa_map

[Jia-Ju Bai]

The kzalloc function is called with GFP_ATOMIC.
But according to driver call graph, it is not in atomic context,
namely no spinlock is held nor in an interrupt handler.

This GFP_ATOMIC is unnecessary, and replace with GFP_KERNEL.
