Will Deacon 3dcaf25993 KVM: arm64: Ensure target address is granule-aligned for range TLBI 
commit 4c36a15673 upstream.

When zapping a table entry in stage2_try_break_pte(), we issue range
TLB invalidation for the region that was mapped by the table. However,
we neglect to align the base address down to the granule size and so
if we ended up reaching the table entry via a misaligned address then
we will accidentally skip invalidation for some prefix of the affected
address range.

Align 'ctx->addr' down to the granule size when performing TLB
invalidation for an unmapped table in stage2_try_break_pte().
