accel/tcg: Restrict page_collection structure to system TB maintainance 

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_fast__locked()
from signed to unsigned.
