Commit6edda04ccc("mm/kmemleak: prevent soft lockup in first object iteration loop of kmemleak_scan()") adds cond_resched() in the first object iteration loop of kmemleak_scan(). However, it turns that the 2nd objection iteration loop can still cause soft lockup to happen in some cases. So add a cond_resched() call in the 2nd and 3rd loops as well to prevent that and for completeness.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
