[PATCH] KVM: VMX: Also clear SGX EDECCSSA in KVM CPU caps when SGX is disabled

[Kai Huang <kai.huang@intel.com>]

When SGX EDECCSSA support was added to KVM in commit 16a7fe3728a8
("KVM/VMX: Allow exposing EDECCSSA user leaf function to KVM guest"), it
forgot to clear the X86_FEATURE_SGX_EDECCSSA bit in KVM CPU caps when
KVM SGX is disabled.  Fix it.
