mei: bus: Check for still connected devices in mei_cl_bus_dev_release()
mei_cl_bus_dev_release() also frees the mei-client (struct mei_cl)
belonging to the device being released.
If there are bugs like the just fixed bug in the ACE/CSI2 mei drivers,
the mei-client being freed might still be part of the mei_device's
file_list and iterating over this list after the freeing will then trigger
a use-afer-free bug.
Add a check to mei_cl_bus_dev_release() to make sure that the to-be-freed
mei-client is not on the mei_device's file_list.
