At the end of function meson_mmc_clk_init, the cfg_div clock was prepared, enabled and configured, but then immediately disabled due to bogus if statements. That made later calls to clk_disable_unprepare executed during module removal to fail with a kernel warning. Fix that by changing the code to disable clock only when it failed to be configured.
