Fix off-by-1 error in RAM migration code

The code for migrating (or savevm-ing) memory pages starts off by creating
a dirty bitmap and filling it with 1s. Except, actually, because bit
addresses are 0-based it fills every bit except bit 0 with 1s and puts an
extra 1 beyond the end of the bitmap, potentially corrupting unrelated
memory. Oops. This patch fixes it.
