KVM: nVMX: Use vmx_segment_cache_clear() instead of open coded equivalent
In prepare_vmcs02_rare(), call vmx_segment_cache_clear() instead of
setting segment_cache.bitmask directly. Using the helper minimizes the
chances of prepare_vmcs02_rare() doing the wrong thing in the future, e.g.
if KVM ends up doing more than just zero the bitmask when purging the
cache.
No functional change intended.
