btrfs: don't needlessly create extent-refs kernel thread
The patch 32b593bfcb58 ("Btrfs: remove no longer used function to run
delayed refs asynchronously") removed the async delayed refs but the
thread has been created, without any use. Remove it to avoid resource
consumption.
Fixes: 32b593bfcb58 ("Btrfs: remove no longer used function to run delayed refs asynchronously")
