[CRYPTO] rmd: Use pointer form of endian swapping operations
This patch converts the relevant code in the rmd implementations to use the pointer form of the endian swapping operations. This allows certain architectures to generate more optimised code. For example, on sparc64 this more than halves the CPU cycles on a typical hashing operation. Based on a patch by David Miller. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
