[PATCH v2 02/12] xfs: return committed status from xfs_trans_roll()

[Brian Foster <bfoster@xxxxxxxxxx>]

Some callers need to make error handling decisions based on whether the
current transaction successfully committed or not. Rename
xfs_trans_roll(), add a new parameter and provide a wrapper to preserve
existing callers.
