lib/nvmf: add explicit iovcnt init to silence LTO related warning 



When Link Time Optimization is enabled, compiler can sometimes produce
additional warnings saying that some variables may be uninitialized.

To supress the warning it is enough to add explicit initialization
of the variable causing the issue, in this case 'iovcnt = 0'.
