KVM: VMX: Tweak the special handling of SECONDARY_EXEC_ENCLS_EXITING in setup_vmcs_config()
SECONDARY_EXEC_ENCLS_EXITING is the only control which is conditionally
added to the 'optional' checklist in setup_vmcs_config() but the special
case can be avoided by always checking for its presence first and filtering
out the result later.
Note: the situation when SECONDARY_EXEC_ENCLS_EXITING is present but
cpu_has_sgx() is false is possible when SGX is "soft-disabled", e.g. if
software writes MCE control MSRs or there's an uncorrectable #MC.
