iomap: support ioends for direct reads
Support using the ioend structure to defer I/O completion for direct
reads in addition to writes. This requires a check for the operation
to not merge reads and writes in iomap_ioend_can_merge. This support
will be used for bounce buffered direct I/O reads that need to copy
data back to the user address space on read completion.
