AIO: Don't plug the I/O queue in do_io_submit()

Asynchronous I/O latency to a solid-state disk greatly increased
between the 2.6.32 and 3.0 kernels. By removing the plug from
do_io_submit(), we observed a 34% improvement in the I/O latency.

Unfortunately, at this level, we don't know if the request is to
a rotating disk or not.

d2 et al.: disable OABI compat

Commit fefc65c201fc50bd4f22602292bbf48c8df23450 removed the requirement
for OABI compatibility back in April due to TLB crashes, but we still
have it on.

There is no reason I can think of to leave this on.
