The last genuine use case for the lpi_list_lock was the global LPI translation cache, which has been removed in favor of a per-ITS xarray. Remove a layer from the locking puzzle by getting rid of it. vgic_add_lpi() still has a critical section that needs to protect against the insertion of other LPIs; change it to take the LPI xarray's xa_lock to retain this property.
