xfs: add nodataio mount option to skip all data I/O
When mounted with nodataio, add the NOSUBMIT iomap flag to all data
mappings passed into the iomap layer. This causes iomap to skip all
data I/O submission and thus facilitates metadata only performance
testing.
For experimental use only. Only tested insofar as fsstress runs for
a few minutes without blowing up.
