[Devel] [PATCH] ploop: don't forget to dec preq->io_count on a error path

[Andrei Vagin]

preq->io_count is incrimented before calling aio_kernel_submit()
and it is decrimented in kaio_rw_aio_complete().

But if aio_kernel_submit() failed , preq->io_count has to be decrimented
before exiting from the function.
