msm: mdss: release all overlay resources if calling process is unknown
There are cases where fb release is called from a process which is
unknown to internal process tracking list. This usually happens when
a crash handlers closes open fds in a kernel worker thread rather than
in process context. In such cases if fb open happens from a completely
new process then it may lead to pipe leakage due to race condition
between unknown process and this new, fb open, process. Prevent this by
releasing all overlay resources when fb release is called from an
unknown process context.
