test/nvmf: do not limit qpairs in nvmf_vhost

Browse Source 
nvmf_vhost test verifies multiple components at once.

In this case the number of NVMe-oF I/O qpairs per controller
is limited to just 4. When a VM connected to the vhost_tgt
is booted, the vhost controller is started/destroyed multiple
times. The quick succession of getting I/O channels and
asynchronous nature of NVMe-oF qpair deletion/creation,
results in exhausting the free qpair ids.

There is no reason to limit the number of NVMe-oF I/O qpairs
in this test. If there ever is a need, a new test could be added
exploring behaviour of components (like vhost) when get I/O channel
fails.

Fixes #2517
