tcg: Fix off-by-one in assert in page_set_flags

Most of the users of page_set_flags offset (page, page + len) as
the end points.  One might consider this an error, since the other
users do supply an endpoint as the last byte of the region.

However, the first thing that page_set_flags does is round end UP
to the start of the next page.  Which means computing page + len - 1
is in the end pointless.  Therefore, accept this usage and do not
assert when given the exact size of the vm as the endpoint.
