[PATCH 2/3] OvmfPkg: revert "any AP in SMM should not wait for the BSP for more than 100 ms"

[Laszlo Ersek <lersek@redhat.com>]

This reverts commit bb0f18b0bce682f6780af997de45bcef146c11ca ("OvmfPkg:
any AP in SMM should not wait for the BSP for more than 100 ms"). That
commit said,

> NOTE: once QEMU becomes capable of synchronous broadcast SMIs, this
> patch and the previous one ("OvmfPkg: use relaxed AP SMM synchronization
> mode") should be reverted, and SmmControl2DxeTrigger() should be
> adjusted instead.
