are flushed implicitly upon Remapping Hardware Caches Invalidation even on
platforms that set RWBF to 1 in capability register. So removed write buffer
flushing as current ACRN issues cache invalidation commands in all cases.

This patch fixes the duplicated functions introduced by cpu caps
modularization.
In cpu caps modularization, function `is_vmx_disabled` was supposed
to be moved from `arch/x86/vmcs.c` to`arch/x86/cpu_caps.c`,
but the original one was not removed.

in vcpuid cache entries.
2) find_vcpuid_entry will return the found entry if local_find_vcpuid_entry
return is not null. Otherwise, call local_find_vcpuid_entry again
when necessary.
In this case, there could eliminate recursion in find_vcpuid_entry.
