ovl: fix origin verification of index dir 



Commit 54fb347e ("ovl: verify index dir matches upper dir")
introduced a new ovl_fh flag OVL_FH_FLAG_PATH_UPPER to indicate
an upper file handle, but forgot to add the flag to the mask of
valid flags, so index dir origin verification always discards
existing origin and stores a new one.
