KVM: VMX: Resume guest immediately when injecting #GP on ECREATE

commit 36d3e211d2303c0aae44305878b009bc73a44219 upstream.

Resume the guest immediately when injecting a #GP on ECREATE due to an
invalid enclave size, i.e. don't attempt ECREATE in the host.  The #GP is
a terminal fault, e.g. skipping the instruction if ECREATE is successful
would result in KVM injecting #GP on the instruction following ECREATE.
