pnfs-obj: Get rid of objlayout_{alloc,free}_io_state
This is part of moving objio_osd to use the ORE.
objlayout_io_state had two functions:
1. It was used in the error reporting mechanism at layout_return.
This function is kept intact.
(Later patch will rename objlayout_io_state => objlayout_io_res)
2. Carrier of rw io members into the objio_read/write_paglist API.
This is removed in this patch.
The {r,w}data received from NFS are passed directly to the
objio_{read,write}_paglist API. The io_engine is now allocating
it's own IO state as part of the read/write. The minimal
functionality that was part of the generic allocation is passed
to the io_engine.
So part of this patch is rename of:
ios->ol_state.foo => ios->foo
At objlayout_{read,write}_done an objlayout_io_state is passed that
denotes the result of the IO. (Hence the later name change).
If the IO is successful objlayout calls an objio_free_result() API
immediately (Which for objio_osd causes the release of the io_state).
If the IO ended in an error it is hanged onto until reported in
layout_return and is released later through the objio_free_result()
API. (All this is not new just renamed and cleaned)
