xfs: xfs_defer_capture should absorb remaining transaction reservation

commit 929b92f64048d90d23e40a59c47adf59f5026903 upstream.

When xfs_defer_capture extracts the deferred ops and transaction state
from a transaction, it should record the transaction reservation type
from the old transaction so that when we continue the dfops chain, we
still use the same reservation parameters.

Doing this means that the log item recovery functions get to determine
the transaction reservation instead of abusing tr_itruncate in yet
another part of xfs.
