Qu Wenruo 9ad15a7301 btrfs-progs: use btrfs_link_subvolume() to replace btrfs_mksubvol() 
The function btrfs_mksubvol() is very different between btrfs-progs and
kernel, the former version is really just linking a subvolume to another
directory inode, but the kernel version is really to make a completely
new subvolume.

Instead of same-named function, introduce btrfs_link_subvolume() and use
it to replace the old btrfs_mksubvol().

This is done by:

- Introduce btrfs_link_subvolume()
  Which does extra checks before doing any modification:
  * Make sure the target inode is a directory
  * Make sure no filename conflict

  Then do the linkage:
  * Add the dir_item/dir_index into the parent inode
  * Add the forward and backward root refs into tree root

- Introduce link_image_subvolume() helper
  Currently btrfs_mksubvol() has a dedicated convert filename retry
  behavior, which is unnecessary and should be done by the convert code.

  Now move the filename retry behavior into the helper.

- Remove btrfs_mksubvol()
  Since there is only one caller utilizing btrfs_mksubvol(), and it's
  now gone, we can remove the old btrfs_mksubvol().
