Since 9458a9a1df, all readers of the dirty bitmaps wait
for the rcu lock, which means that they wait until the end
of any executing TranslationBlock.
As a consequence, there is no need for the actual access
to happen in between the _prepare and _complete. Therefore,
we can improve things by merging the two functions into
notdirty_write and dropping the NotDirtyInfo structure.
In addition, the only users of notdirty_write are in cputlb.c,
so move the merged function there. Pass in the CPUIOTLBEntry
from which the ram_addr_t may be computed.
