Currently the sound driver uses qmi workqueues for any qmi request sequences to execute, however while doing fast disconnect/connect there is a possbility that the worker thread race between each other which might lead to a scenario where in between the connect sequence the disconnect might interfere and the endpoint might get freed. This might lead to a null pointer deferences in the process used by the hcd. Fix this by making use of the chip-s usage_count to serialize these processes. The disconnect in card drvier will wait for the usage_count to be decreased to 0 in order to execute the disconnect sequences which woudl make sure that the connect runs completely before disconnect.
