[restored issue] - Livelock in geqrf_hqr
The commit fef23203 introduces a livelock when trying to use geqrf_hqr testing
For example the following on plafrim with 9 bora nodes reserved in exclusive and 1 task per node
mpiexec -n 9 ./testing/chameleon_stesting -o geqrf_hqr -P 3 -t 34 -g 0 -m 2520 -n 2520 -k 1 -b 280
is livelocking. The same with larger matrices n=5040, 10080, etc
