ASoC: starfive: Fix an error check in jh7110_tdm_clk_reset_get()

Browse Source 
Fix the check for devm_reset_control_array_get_exclusive() return value.
The devm_reset_control_array_get_exclusive() function may return NULL if
it's an optional request. If optional is intended then NULL should not
be treated as an error case, but as a special kind of success case. So
here the IS_ERR() is used to check better.
