ALSA: hda - Fix a failure of micmute led when having multi adcs
commit 4875a5f7218068cdeea5f998330dfa3d118b2fea upstream.
On a Dell laptop, there is no global adcs for all input devices, so
the input devices use the different adc, as a result, dyn_adc_switch
is set to true.
In this situation, it is safe to control the micmute led according to
user's choice of muting/unmuting the current input device, since only
current input device path is active, while other input device paths
are inactive and powered down.
