Function domain_set_node_affinity() is responsible for
XEN_DOMCTL_setnodeaffinity domctl-op, and shall be wrapped with
CONFIG_MGMT_HYPERCALLS. Otherwise it will become unreachable codes when
MGMT_HYPERCALLS=n, and hence violating Misra rule 2.1.

v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- wrap XEN_DOMCTL_setnodeaffinity-case and xenctl_bitmap_to_nodemask()
transiently
---
v2 -> v3:
- address "violating Misra rule 2.1" in commit message
- remove transient wrapping around XEN_DOMCTL_setnodeaffinity-case
