greybus: light: Initialize mutex before using it

Light protocol driver is suffering from the same issue that was fixed in
camera driver earlier (commit a7c3b0c3c8da).

Big cleanup function is used instead of fine grained control in the
error path, and in one of the cases the mutex was found uninitialized
and so the oops seen in SW-6752.

Initialize the mutex before any code can access it.

Compile tested only.
