Fix race condition for non-open/create operations happening after a doom.                                                                                                                                                                                                                                   

Doom used not to be treated as a regular operation in the sense that it didn't
use the pending operations queue. Therefore it was possible to kick off a doom
operation on an entry while another one was happening.
