Oliver Upton f6a27d6dc5 KVM: arm64: Drop last page ref in kvm_pgtable_stage2_free_removed() ... The reference count on page table allocations is increased for every 'counted' PTE (valid or donated) in the table in addition to the initial reference from ->zalloc_page(). kvm_pgtable_stage2_free_removed() fails to drop the last reference on the root of the table walk, meaning we leak memory. Fix it by dropping the last reference after the free walker returns, at which point all references for 'counted' PTEs have been released.
