When a keep alive TA instance panics, it continues to exist and
blocks all further use of the TA until the next reboot of the system.
Moreover, when a new session is trying to be created for
the panicked TA (while another session to that TA is still opened),
the system hangs.
This change releases panicked TA context and clears all references to
the released context when the TA panics regardless the TA properties.
This allows keep alive TA instances to be created back after they have
panicked without needing to reboot OP-TEE core.
Sessions on panicked TAs have to be closed by the client by calling
the proper API when session client is scheduled back.
