KVM: x86/mmu: Collapse kvm_flush_remote_tlbs_with_{range,address}() together
Collapse kvm_flush_remote_tlbs_with_range() and
kvm_flush_remote_tlbs_with_address() into a single function. This
eliminates some lines of code and a useless NULL check on the range
struct.
Opportunistically switch from ENOTSUPP to EOPNOTSUPP to make checkpatch
happy.
