[PATCH v2 07/18] erofs: convert iomap ops to ->iomap_next()

[Joanne Koong <joannelkoong@gmail.com>]

Convert erofs iomap_ops to the new ->iomap_next() callback. This uses the
iomap_process() helper, which finishes the previous mapping if needed
and produces the next one. No functional changes are intended.
