KVM: arm64: Remove redundant setting of HCR_EL2 trap bit

Browse Source 
In hVHE mode, HCR_E2H should be set for both protected and
non-protected VMs. Since commit b56680de9c ("KVM: arm64:
Initialize trap register values in hyp in pKVM"), this has been
fixed, and the setting of the flag here is redundant.
