ASoC: ti: omap-dmic: Fix IS_ERR() vs NULL check bug in omap_dmic_select_fclk()

clk_get_parent() returns NULL when the clock has no parent (or when the
input clk is NULL); it never returns an ERR_PTR. The current IS_ERR(mux)
check therefore never triggers - a NULL return falls through silently
to clk_set_parent(NULL, parent_clk), which simply fails with -EINVAL.

Use a NULL check so the dedicated error path runs and the prior
clk_get() reference is released via clk_put().
