aio: drop needless assignment in aio_read()

Commit 84c4e1f89fef ("aio: simplify - and fix - fget/fput for io_submit()")
refactored aio_read() and some error cases into early return, which made
some intermediate assignment of the return variable needless.

Drop this needless assignment in aio_read().

No functional change. No change in resulting object code.
