Krishna Kurapati 3b14c6f914 sound: usb: qmi: Prevent Null pointer deference due to connect/disconnect 
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.
