mm/rmap: rename page__anon_vma to anon_vma for consistency 

Patch series "mm: minor cleanups in rmap", v3.

Minor cleanups in mm/rmap.c:

- Rename a local variable for consistency
- Fix a typo in a comment

No functional changes.


This patch (of 2):

Rename local variable page__anon_vma in page_address_in_vma() to anon_vma.
The previous naming convention of using double underscores (__) is
unnecessary and inconsistent with typical kernel style, which uses single
underscores to denote local variables.  Also updated comments to reflect
the new variable name.

Functionality unchanged.
