4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Gruenbacher <agruenba@xxxxxxxxxx>
[ Upstream commit 2d8d7990619878a848b1d916c2f936d3012ee17d ]
Add a missing initialization of variable ap in setattr_chown().
Without, chown() may be able to bypass quotas.
