If cluster goes into headless stage and wait up to 3 mins
which is currently the timeout of MDS_AWAIT_ACTIVE_TMR_VAL,
amfnd will receive another NCSMDS_DOWN, and then delete
all buffered messages. As a result, the headless recovery
is impossible because these buffered messages are deleted.
Patch ignores the second NCSMDS_DOWN.
