The locking rules in the driver came from era when sysfs attributes could live past the point of time when device would be unbound from the driver, and so used module-global semaphore (potentially shared between multiple yealink devices). Thankfully these times are long gone and attributes will not be accessible once they are removed. Simplify the logic by moving to per-device mutex, stop checking if there is driver data instance attached to the interface, and use guard notation to acquire the mutex.
