Currently the link_state is uninitialized and the default value is 0(U0)
before the first time we start the udc, and after we start the udc then
stop the udc, the link_state will be undefined.
We may have the following warnings if we start the udc again with
an undefined link_state:

(cherry picked from commit a0ad85ae86)
This reverts commit c139ec131a.
This patch needs a series of related patches, if we only pick
this upstream patch, the UVC gadget can't work normally. So
just revert it.
As a side effect, the audio source function doesn't work.
However, the audio source function is a only used for linux
linaro, and we suggest to use UAC1 or UAC2 instead of audio source.
