io_uring: kiocb_done() should *not* trust ->ki_pos if ->{read,write}_iter() failed

BugLink: https://bugs.launchpad.net/bugs/2043730

->ki_pos value is unreliable in such cases. For an obvious example,
consider O_DSYNC write - we feed the data to page cache and start IO,
then we make sure it's completed. Update of ->ki_pos is dealt with
by the first part; failure in the second ends up with negative value
returned _and_ ->ki_pos left advanced as if sync had been successful.
In the same situation write(2) does not advance the file position
at all.
