xfs: kill xfs_iomap
Opencode the xfs_iomap code in it's two callers. The overlap of
passed flags already was minimal and will be further reduced in the
next patch.
As a side effect the BMAPI_* flags for xfs_bmapi and the IO_* flags
for I/O end processing are merged into a single set of flags, which
should be a bit more descriptive of the operation we perform.
Also improve the tracing by giving each caller it's own type set of
tracepoints.
