Subject: [PATCH] S-ACM entry ver 0x200 does not contain requested FMS&mask

From: Dakota Chiang <dakota.chiang@intel.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4198

After commit 1e1e35bb3b2fceea75ad97968da4b31f059dcb4c,
FIT Type 2 ACM entry is not generated as expected with given -I arguments.
FMS/FMS value is overridden by GetAcmFms().

This patch detects whether FMS/FMS Mask is already assigned with -I argument. If it's not zero, skip invoking GetAcmFms().
