Re: ceph-objectstore-tool import failures

[David Zafman <dzafman@redhat.com>]

Have not seen this as an assert before.  Given the code below in 
do_import() of master branch the assert is impossible (?).

   if (!curmap.have_pg_pool(pgid.pgid.m_pool)) {
     cerr << "Pool " << pgid.pgid.m_pool << " no longer exists" << 
std::endl;
     // Special exit code for this error, used by test code
     return 10;  // Positive return means exit status
   }
