KVM: x86: Free wbinvd_dirty_mask if vCPU creation fails
commit 16be9ddea268ad841457a59109963fff8c9de38d upstream.
Free the vCPU's wbinvd_dirty_mask if vCPU creation fails after
kvm_arch_vcpu_init(), e.g. when installing the vCPU's file descriptor.
Do the freeing by calling kvm_arch_vcpu_free() instead of open coding
the freeing. This adds a likely superfluous, but ultimately harmless,
call to kvmclock_reset(), which only clears vcpu->arch.pv_time_enabled.
Using kvm_arch_vcpu_free() allows for additional cleanup in the future.
Fixes: f5f48ee15c2ee ("KVM: VMX: Execute WBINVD to keep data consistency with assigned devices")

[bwh: Backported to 3.16: Also delete the preceding fx_free(), since
kvm_arch_vcpu_free() calls it.]
