Back-ported the fix for bug #12831587 from mysql-5.6 code line.

The comment for the fix commit says:
Due to the changes required by ICP we first copy a row from the InnoDB
format to the MySQL row buffer and then copy it to the pre-fetch queue.
This was done for the non-ICP code path too. This change removes the
double copy for the latter.

Applied the patch from mysql-5.6 code line that fixed
a significant performance drop for high concurrency bechmarks
(bug #11765850 - 58854).

Here's the comment of the patch commit:

The bug is that the InnoDB pre-fetch cache was not being used in
row_search_for_mysql(). Secondly the changeset that planted the
bug also introduced some inefficient code. It would read an extra
row, convert it to MySQL row format (for ICP==off), copy the row
to the pre-fetch cache row buffer, then check for cache overflow
and dequeue the row that was pushed if there was a possibility of
a cache overflow.
