[LU-18776] DoM discard callback can lead to recursion and stack corruption - Whamcloud Community JIRA

the mdt_dom_discard_data() has two problems to resolve:

no protection from multiple calls for the same object. That causes many discard locks to be taken waiting each other, while only one is needed
mdt_dom_discard_cb() may cause another call to cancel callback in the same thread, entering into recursion. With many waiting locks (see #1) that causes stack overflow
