ovl: add ovl_upper_mnt_userns() wrapper
Add a tiny wrapper to retrieve the upper mount's idmapping. Have it
return the initial idmapping until we have prepared and converted all
places to take the relevant idmapping into account. Then we can switch
on idmapped layer support by having ovl_upper_mnt_userns() return the
upper mount's idmapping.
