[syslinux] [PATCH 04/19] core: Only adjust screen if we're in text mode

[Matt Fleming]

From: Matt Fleming <matt.fleming at intel.com>

A bug was introduced in commit 9f51b69d ("core: Reimplement lots asm
code in C") when converting the old asm comapi_usingvga function into
C. We only want to adjust the screen if we're not using VGA.
