crypto: glue_helper - remove the le128_gf128mul_x_ble function
The le128_gf128mul_x_ble function in glue_helper.h is now obsolete and can be replaced with the gf128mul_x_ble function from gf128mul.h. Signed-off-by: Ondrej Mosnacek <omosnacek@gmail.com> Reviewd-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
