fbsplash: use virtual y size in mmap size calculations
The virtual y can be larger - and we can be even writing there since
we are taking into account the y offset. Avoids possible crash.
But use it only if set, seems it is not set if virtual area is not
allocated (though, often fbcon allocates some scrollback area).
