x86/efi: Replace GFP_ATOMIC with GFP_KERNEL in efi_query_variable_store()
efi_query_variable_store() does an atomic kzalloc() unnecessarily,
because we can never get this far when called in an atomic context,
namely when nonblocking == 1.
Replace it with GFP_KERNEL.
This was found by the DCNS static analysis tool written by myself.
