Reset target sdk version of ParseTypeImpl

In device booting, PackageParser2 uses a thread
local ParseTypeImpl obj as shared result and reset
it before parsing everty time. But it doesn't reset
the target sdk version, which could make deferError
returned unexpected error, cause apk scaned failed
and deleted by the system.
