staging: lustre: lnet: remove dead code and useless wrapper
After removing commented out code, ksocknal_csum() becomes a useless wrapper for crc32_le(). Remove it, and instead call crc32_le() directly. Fixes the following checkpatch warning: WARNING: space prohibited before semicolon Signed-off-by: Dmitriy Cherkasov <dmitriy@oss-tech.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
