[PATCH] btrfs: fix stale reference to __btrfs_alloc_chunk

[Anand Jain <anand.jain@oracle.com>]

__btrfs_alloc_chunk() is renamed to btrfs_alloc_chunk() and then to
btrfs_create_chunk() in the commits 11c67b1a40b0 and ad6b24de1d50
respectively. And left the stale reference to __btrfs_alloc_chunk().
Fix them.

I am fine if you want to rollup this patch to the patch (btrfs: rename
btrfs_alloc_chunk to btrfs_create_chunk) and add my RB, or add this patch
as a new one.

Thx.
