This refactors mmqv to unify the handling of parameters between host and device side code, avoideing duplication in calculateing nwarps and rows_per_cuda_block. Also explicitly handles wave_size != 32, for the minor benefit of getting us out of shared memory into warp level primitives one iteration earlier.
