test/nvmf: Replace [ with [[ test in allocate_nic_ips()

Browse Source 
The former will force Bash to complain if $ip consists of more than
one ip address. E.g.:

  1:08:55	# '[' -z 192.168.121.37 192.168.121.36 ']'
  line 104: [: 192.168.121.37: binary operator expected

The alternative is to properly quote the $ip inside [, however, [[
is always the safest approach.
