ALSA: hda/conexant: Add NULL check for dc_mode_path

Browse source

snd_hda_add_new_path() returns NULL when no path exists between the
given NIDs, but olpc_xo_update_mic_pins() passes dc_mode_path
straight to snd_hda_activate_path() which dereferences it without
checking. Add the missing NULL guards, same as the local path
variable already has in the same function.
