KVM: arm64: Use TLBI_TTL_UNKNOWN in __kvm_tlb_flush_vmid_range()

Commit c910f2b65518 ("arm64/mm: Update tlb invalidation routines for
FEAT_LPA2") updated the __tlbi_level() macro to take the target level
as an argument, with TLBI_TTL_UNKNOWN (rather than 0) indicating that
the caller cannot provide level information. Unfortunately, the two
implementations of __kvm_tlb_flush_vmid_range() were not updated and so
now ask for an level 0 invalidation if FEAT_LPA2 is implemented.

Fix the problem by passing TLBI_TTL_UNKNOWN instead of 0 as the level
argument to __flush_s2_tlb_range_op() in __kvm_tlb_flush_vmid_range().
