ovl: fix origin verification of index dir
Commit 54fb347e836f ("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.
