Check whether memory client reset is already asserted in order to prevent DMA-flush error on trying to re-assert an already asserted reset. This becomes a problem once PMC GENPD is enabled to use memory resets since GENPD will get a error and fail to toggle power domain. PMC GENPDs can't be toggled safely without holding memory reset on Tegra and we're about to fix this.
