[PATCH v2 11/26] xen/domctl: wrap domain_set_node_affinity() with CONFIG_MGMT_HYPERCALLS

[Penny Zheng <Penny.Zheng@xxxxxxx>]

Function domain_set_node_affinity() is responsible for
XEN_DOMCTL_setnodeaffinity domctl-op, and shall be wrapped with
CONFIG_MGMT_HYPERCALLS
Wrap XEN_DOMCTL_setnodeaffinity-case and xenctl_bitmap_to_nodemask()
transiently with CONFIG_MGMT_HYPERCALLS, and it will be removed when
introducing CONFIG_MGMT_HYPERCALLS on the common/domctl.c in the last.

Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx>
---
v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- wrap XEN_DOMCTL_setnodeaffinity-case and xenctl_bitmap_to_nodemask()
transiently
