Lz4NativeCompressor fails uncleanly if native is not available

[JanecekPetr]

On Windows the native implementations of (de)compressors are not available. They usually fail cleanly with an okay message, however Lz4NativeCompressor instead fails with

java.lang.IllegalArgumentException: The provided allocation size is negative: -1

There's a field which should only be assigned after the is-native-enabled check passes in the constructor.
