KVM: VMX: don't use "unsigned long" in vmx_vcpu_enter_exit()

__vmx_vcpu_run_flags() returns "unsigned int" and uses only 2 bits of it
so using "unsigned long" is very much pointless.  Furthermore,
__vmx_vcpu_run() and vmx_spec_ctrl_restore_host() take an "unsigned int",
i.e. actually relying on an "unsigned long" value won't work.
