LU-16112 build: ki_complete removed unused argument

Linux commit v5.15-rc6-145-g6b19b766e8f0
   fs: get rid of the res2 iocb->ki_complete argument

Prior to 4.1 Linux provided an aio_complete(iocb, res, res2)
which propagated res2 to io_event.res2. This functionality
migrated to iocb->ki_complete().

Provide a wrapper around iocb->ki_complete() to use
aio_complete() or iocb->ki_complete() as appropriate.
