ecore_drm2: Don't fail if there's no boot_vga device

In a multi-seat configuration it's quite likely that only one
seat will have a boot_vga device.

While we should use the boot_vga device if possible, we shouldn't
fail just because a seat's gpu isn't the boot_vga device.  Fallback
to the last viable drm device we saw.
