Commit 13bea86623be ("thermal/of: Remove of_thermal_get_crit_temp()")
removed the function of_thermal_get_crit_temp() and this is causing a
NULL pointer deference crash when attempting to call the 'get_crit_temp'
function pointer because this function pointer is no longer initialised.
Fix this by replacing the call to the 'get_crit_temp' function pointer
with a call to the function thermal_zone_get_crit_temp() instead.
