Boris Burkov 585c5732ca btrfs: qgroup: convert PREALLOC to PERTRANS after record_root_in_trans 
commit 211de93367304ab395357f8cb12568a4d1e20701 upstream.

The transaction is only able to free PERTRANS reservations for a root
once that root has been recorded with the TRANS tag on the roots radix
tree. Therefore, until we are sure that this root will get tagged, it
isn't safe to convert. Generally, this is not an issue as *some*
transaction will likely tag the root before long and this reservation
will get freed in that transaction, but technically it could stick
around until unmount and result in a warning about leaked metadata
reservation space.

This path is most exercised by running the generic/269 fstest with
CONFIG_BTRFS_DEBUG.
