test/nvmf/nvme-cli: don't run nvme-cli as secondary process

Browse Source 
nvme-cli in NVMf tests currently fails to initialize
the NVMe driver and exits straight away [1]. It expects
the primary process to initialize the driver first, but
since the primary process doesn't operate on any NVMe
devices, it doesn't initialize the driver at all.

Fix this by running nvme-cli without multi-process mode.
In NVMf tests, nvme-cli is only used to discover, connect
and disconnect from an SPDK NVMf target. It does not need
to access any shared memory resources.

This wasn't an issue before, because we used an outdated
DPDK version for nvme-cli which didn't detect any other
shared memory processes of SPDK.

[1] nvme.c: 337:nvme_driver_init: *ERROR*: primary process
is not started yet
