xfs: initialize iomap->flags in xfs_bmbt_to_iomap
Currently we don't overwrite the flags field in the iomap in xfs_bmbt_to_iomap. This works fine with 0-initialized iomaps on stack, but is harmful once we want to be able to reuse an iomap in the writeback code. Replace the shared parameter with a set of initial flags an thus ensures the flags field is always reinitialized.
