KVM: x86: Revert "KVM: x86: Mark GPRs dirty when written"
Revert the dirty/available tracking of GPRs now that KVM copies the GPRs
to the GHCB on any post-VMGEXIT VMRUN, even if a GPR is not dirty. Per
commit
de3cd117ed2f ("KVM: x86: Omit caching logic for always-available
GPRs"), tracking for GPRs noticeably impacts KVM's code footprint.
