This takes the approach from Dave, but adds a new flag instead of abusing
the nowait one, and keeps a simpler calling convention for iomap_dio_rw.

Changes since v2:
 - add another sanity check in __iomap_dio_rw
 - rename IOMAP_DIO_UNALIGNED to IOMAP_DIO_OVERWRITE_ONLY
 - use more consistent parameter naming
 - improve a few comments
 - cleanup an if statement

Changes since v1:
 - rename the new flags
 - add an EOF check for subblock I/O
 - minor cleanups

Changes since v3:
 - further comment improvements
 - micro-optimize an alignment check
