vmware_vga: Remove duplicated info from local state

Removed info from vmsvga_state that is available from elsewhere and
thus was duplicated here unnecessarily.

vmware_vga: Return a value for FB_SIZE before the device is enabled

According to the documentation drivers using this device should read
FB_SIZE before enabling the device to know what memory to map. This
would not work if we return 0 before enabled. The docs also mention
reading SVGA_REG_DEPTH but not writing it. (Only SVGA_REG_BITS_PER_PIXEL
can be written but we don't really support that either.)

vmware_vga: Allow simple drivers to work without using the fifo

Postpone stopping the dirty log to the point where the command fifo is
configured to allow drivers which don't use the fifo to work too.
(Without this the picture rendered into the vram never got to the
screen and the DIRECT_VRAM option meant to support this case was
removed a year ago.)
