[PATCH v2 03/11] KVM: x86: Drop local pvclock_flags variable in kvm_guest_time_update()

[Sean Christopherson <seanjc@google.com>]

Drop the local pvclock_flags in kvm_guest_time_update(), the local variable
is immediately shoved into the per-vCPU "cache", i.e. the local variable
serves no purpose.

No functional change intended.
