get_user_mapping_size() uses vabits_actual and CONFIG_PGTABLE_LEVELS to provide the starting point for a table walk. This is fine for LVA, as the number of translation levels is the same regardless of whether LVA is enabled. However, with LPA2, this will no longer be the case, so let's derive the number of levels from the number of VA bits directly.
