reduce: use consistent callback names

Browse Source 
There are a sequence of operations needed for both
read and write I/O.  For example, on a write I/O,
we may need to do a read, modify the chunk, then
write the data back to disk.

For read I/O, the name of the callback is
_read_read_done - the first "read" indicates the
I/O type, the second "read" indicates the disk read
part of the sequence.

The write I/O steps aren't using this same naming
convention, so change that here.  This will be
important in upcoming patches where we'll be adding
compress/decompress steps into the I/O pipeline -
having a consistent naming strategy will make the code
easier to follow.
