linux-user: Rename validate_guest_space => init_guest_commpage 

init_guest_commpage is a much more honest description of what the function
does.  validate_guest_space not only suggests that the function has no
side-effects, but also introduces confusion as to why it is only needed on
32-bit ARM targets.
