Goffredo Baroncelli efbe4ab8e2 btrfs-progs: add path opening helpers without dirstream
For historical reasons the helpers [btrfs_]open_dir... return also
the 'DIR *dirstream' value when a directory is opened.

However this is never used. So avoid calling diropen() and return only
the fd.  This is a preparatory patch.
