[PATCH-for-8.0 5/5] accel/tcg: Restrict page_collection structure to system TB maintainance

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Only the system emulation part of TB maintainance uses the
page_collection structure. Restrict its declaration (and the
functions requiring it) to tb-maint.c.

Convert the 'len' argument of tb_invalidate_phys_page_locked_fast()
from signed to unsigned.
