btrfs-progs: replace btrfs_open_dir with btrfs_open_dir_fd 

For historical reasons the helpers [btrfs_]open_dir... return also
the 'DIR *dirstream' value when a directory is opened.

Replace btrfs_open_dir() with btrfs_open_dir_fd() removing
any reference to the unused/useless dirstream variables.
Calling btrfs_open_dir_fd() with only the path is equivalent to
btrfs_open_dir(_, _, 1).
