ovl: pass ofs to creation operations

Browse source 
[ Upstream commit 576bb26345 ]

Pass down struct ovl_fs to all creation helpers so we can ultimately
retrieve the relevant upper mount and take the mount's idmapping into
account when creating new filesystem objects. This is needed to support
idmapped base layers with overlay.
