net: cisco: enic: Replace GFP_ATOMIC with GFP_KERNEL 

vnic_dev_register(), vnic_rq_alloc_bufs() and vnic_wq_alloc_bufs()
are never called in atomic context.
They call kzalloc() with GFP_ATOMIC, which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.
