[PATCH v2 0/2] btrfs: subvolume deletion vs. snapshot fixes

[Omar Sandoval <osandov@osandov.com>]

From: Omar Sandoval <osandov@fb.com>

Hi,

This small series fixes a couple of bugs that can happen when trying to
snapshot a deleted subvolume. Patch 1 fixes a filesystem abort that we
hit in production. Patch 2 fixes another issue that Sweet Tea spotted
when reviewing patch 1.

An fstest was sent previously [1].

Thanks!

Changes from v1 [2]:

- Rebased on latest misc-next.
- Added patch 2.
