    marker: Fix inode value in loc, in setxattr fop

    On recieving a rename fop, marker_rename() stores the,
    oldloc and newloc in its 'local' struct, once the rename
    is done, the xtime marker(last updated time) is set on
    the file, but sending a setxattr fop. When upcall
    receives the setxattr fop, the loc->inode is NULL and
    it crashes. The loc->inode can be NULL only in one valid
    case, i.e. in rename case where the inode of new loc
    can be NULL. Hence, marker should have filled the inode
    of the new_loc before issuing a setxattr.

    marker_rename_cbk was already fixed in a previous commit.
    Fixing marker_rename_done to send valid inode in this commit.

    Also in upcall check for NULL inode so that there is no crash.
