mm/damon/vaddr: remove comparison between mm and last_mm when checking region accesses
The damon regions that belong to the same damon target have the same 'struct mm_struct *mm', so it's unnecessary to compare the mm and last_mm objects among the damon regions in one damon target when checking accesses. But the check is necessary when the target changed in '__damon_va_check_accesses()', so we can simplify the whole operation by using the bool 'same_target' to indicate whether the target changed.

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.
