Sasha Kotchubievsky a8dd54792c perf: Fix integer overflow 
perf application can't generate IO for NVMe namespace with
 more than 4G size.

 Example of error:
 "Attached to NVMe over Fabrics controller at 1.1.75.1:1023:
 nqn.2016-06.io.spdk.r-dcs75:rd0
 WARNING: controller SPDK bdev Controller (SPDK000DEADBEAF00   ) ns 1 has
 invalid ns size 0 / block size 4096 for I/O size 4096
 WARNING: Some requested NVMe devices were skipped
 No valid NVMe controllers or AIO devices found"

 ns_size variable is uint32_t, spdk_nvme_ns_get_size function
 returns uint64_t. Result can exceed the maximum size of
 uint32_t and ns_size remains 0.

 The issue introduced by commit: f2462909

Compiling perf on FreeBSD

To use perf test on FreeBSD over NVMe-oF, explicitly link userspace library of HBA. For example, on a setup with Mellanox HBA,

LIBS += -lmlx5
