Laszlo Ersek 550acd08e5 OvmfPkg/IoMmuDxe: generalize IoMmuUnmap() to IoMmuUnmapWorker()
IoMmuUnmapWorker() is identical to IoMmuUnmap(), it just takes an
additional BOOLEAN parameter called "MemoryMapLocked".  If the memory map
is locked, IoMmuUnmapWorker() does its usual job, but it purposely leaks
memory rather than freeing it. This makes it callable from
ExitBootServices() context.

Turn IoMmuUnmap() into a thin wrapper around IoMmuUnmapWorker() that
passes constant FALSE for "MemoryMapLocked".
