Yin Fengwei db46df940e DM: add init/deinit function for mevent ...

Current, mevent cleanup path has issue. There are possible
following calling sequence happen when reboot/poweroff UOS:
 1. mevent_dispatch() calls mevent_destroy
 2. do_close_post calls some virtual device deinit to delete
    mevent.

This patch introduce mevent init/deinit to make sure:
 1. mevent init
 2. mevent_add is called when init virtual device
 3. mevent_del is called when deinit virtual device
 4. mevent deinit
