Subject: [PATCH] test/nvmf: reduce the resource consumption in autotest

When testing test/nvmf/lvol/nvmf_lvol.sh in test pool, Linux
reported error with "Failed to write to /dev/nvme-fabrics:
Cannot allocate memory" sometimes when connecting to target.
While here, reduce the test cycle count to avoid such error.
