qcacmn: stub core_ctl_set_boost if not defined

In hif_napi.c, we are calling this kernel API core_ctl_set_boost. This
API is only present in the kernel if the feature CONFIG_SCHED_CORE_CTL
is present. In case the feature is not present in the kernel, it will
result in a compilation error.
Create a new internal API hif_napi_core_ctl_set_boost as a wrapper
around the kernel API. The new API is stubbed in case the kernel feature
is not present.
