This function has two users, who use it incompatibly.
In tlb_flush_page_by_mmuidx_async_0, when flushing a

Use the pc coming from db->pc_first rather than the TB.
Use the cached host_addr rather than re-computing for the
first page. We still need a separate lookup for the second
page because it won't be computed for DisasContextBase until
the translator actually performs a read from the page.
