LU-1095 debug: Improve messages for fake requests

Update the console filter to correctly handle fake requests and
squelched the lov_update_create_set() message for the
-ETIMEDOUT/-ENOTCONN case.

 LustreError: 7872:0:(lov_request.c:693:lov_update_create_set()) error
 creating fid 0x104c5e0b sub-object on OST idx 53/2: rc = -107
