vmsvga: move fifo sanity checks to vmsvga_fifo_length
Sanity checks are applied when the fifo is enabled by the guest
(SVGA_REG_CONFIG_DONE write).  Which doesn't help much if the guest
changes the fifo registers afterwards.  Move the checks to
vmsvga_fifo_length so they are done each time qemu is about to read
from the fifo.
