DM: make removing vGSI capability option as local

Browse Source 
Current option of removing vGSI capability is global, which exposes
vIOAPIC link for all ptdev even only one need this. This patch makes
it as ptdev local option to lower the system level impact. To keep
vGSI for MSI capable ptdev, just explicitly append ",keep_gsi" in
option list, like "-s 14,passthru,0/e/0,keep_gsi"
