mmc: tmio, renesas_sdhi: Remove unneeded NULL check



The inconsistent NULL checking in this function causes static checker
warnings.

    drivers/mmc/host/renesas_sdhi_sys_dmac.c:360 renesas_sdhi_sys_dmac_issue_tasklet_fn()
    error: we previously assumed 'host' could be null (see line 351)

On reviewing this code, "host" can't ever be NULL so we can just remove
the check.
