Volume top tests are failing in BVT test as cli is timing out for below command and for subsequent test are failing as cli returning error "Another transaction is in progress for test-vol. Please try again after sometime."

The test is a negative test where, following command s run for a wrong brick.

How reproducible:
Always

Steps to Reproduce:
1. Create volume, start it
2. Mount it on client. Run IO
for i in `seq 1 100`; do dd if=/dev/zero of=/mnt/fuse/$i bs=128K count=100 2>&1 1>/dev/null; dd if=/mnt/fuse/$i of=/dev/zero bs=128K count=100 2>&1 1>/dev/null; done
3.  gluster volume top $volname open
4. Run volume top for a brick which is not part of the volume.
gluster volume top $volname open brick $IP:/tmp/brick
5. gluster volume top $volname read

Actual results:
