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.
