Return "Unsupported" from VESA accelerant mode setting

Browse Source 
Currently, when trying to change settings in Screen preferences on
a system which uses VESA driver on UEFI system, the displayed error
message is "Invalid argument". This commit simply changes returned
error code to B_UNSUPPORTED, so that in the UI we show
"Operation not supported" error.
