[XEN PATCH v2 3/3] xen: fix violations of MISRA C:2012 Rule 3.1



In the files modified by this patch there are a few occurrences of nested '//'
character sequences inside C-style comment blocks, which violate Rule 3.1.
The patch aims to resolve those by removing the nested comments.

In the file `xen/common/xmalloc_tlsf.c' the comment has been deleted,
following the suggestion of a review comment.

In the file `xen/include/xen/atomic.h' the nested comment has been removed,
since the code sample is already explained by the preceding comment.

Signed-off-by: Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx
Changes:
- Resending the patch with the right maintainers in CC.
Changes in V2:
- Split the patch into a series and reworked the fix.
- Apply the fix to the arm32 `flushtlb.h' file, for consistency
