mmc: card: Fix broken clock gating



The commit '77dacd' misses to add mmc_host_clk_release() in the
completion path of a CQ request i.e., in mmc_blk_cmdq_complete_rq().
Hence, the reference counter of clocks (host->clk_requests) never
becomes 0, preventing the clocks from gating. However, the clocks
are still turned off through other power management features such as
runtime/system suspend.
