Christoph Hellwig be225fec72 xfs: remove the io_type field from the writeback context and ioend
The io_type field contains what is basically a summary of information
from the inode fork and the imap.  But we can just as easily use that
information directly, simplifying a few bits here and there and
improving the trace points.
