* @fn void deinit_ss7OmMIB(void)
* @brief deinitialization routine.
*
* This is called before the agent is unloaded. At a minimum, deregistration of the MIB variables
* structure (ss7OmMIB_variables) should take place here. By default, the function also
* deregisters the the configuration file handlers for the MIB variables and table rows.
*
* Additional deregistrations that may be required here are calls to unregister_readfd(),
* unregister_writefd() and unregsiter_exceptfd() for unhooking from the snmpd event loop, but only
* when used as a loadable module. By default if a read file descriptor exists, it is unregistered.
