linux-user: Do not use guest_addr_valid for h2g_valid

This is the only use of guest_addr_valid that does not begin
with a guest address, but a host address being transformed to
a guest address.

We will shortly adjust guest_addr_valid to handle guest memory
tags, and the host address should not be subjected to that.

Move h2g_valid adjacent to the other h2g macros.
