[PATCH v4 09/24] xen/domctl: wrap vcpu_affinity_domctl() with CONFIG_MGMT_HYPERCALLS

[Penny Zheng <Penny.Zheng@xxxxxxx>]

Function vcpu_affinity_domctl() is responsible for
XEN_DOMCTL_{getvcpuaffinity,setvcpuaffinity} 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.
Tracking its calling chain, vcpuaffinity_params_invalid() also needs
wrapping too

v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- wrap XEN_DOMCTL_{getvcpuaffinity,setvcpuaffinity}-case transiently
---
v2 -> v3:
- adapt to changes of "remove vcpu_set_soft_affinity()"
- address "violating Misra rule 2.1" in commit message
- remove transient wrapping around 
XEN_DOMCTL_{getvcpuaffinity,setvcpuaffinity}-case
---
v3 -> v4
- wrap vcpuaffinity_params_invalid()
