[GIT PULL] Btrfs fixes for 5.9-rc8

[David Sterba]

Hi,

two more fixes. One is for a lockdep warning/lockup (also caught by
syzbot), that one has been seen in practice.  Regarding the other syzbot
reports mentioned last time, they don't seem to be urgent and reliably
reproducible so they'll be fixed later.

The second fix is for a potential corruption when device replace
finishes and the in-memory state of trim is not copied to the new
device.

Please pull, thanks.
