Btrfs: fix joining the same transaction handler more than 2 times
If we flush inodes with pending delalloc in a transaction, we may join
the same transaction handler more than 2 times.
The reason is:
Task use_count of trans handle
commit_transaction 1
|-> btrfs_start_delalloc_inodes 1
|-> run_delalloc_nocow 1
|-> join_transaction 2
|-> cow_file_range 2
|-> join_transaction 3
In fact, cow_file_range needn't join the transaction again because the caller
have joined the transaction, so we fix this problem by this way.
