Introduce two new function to calculate the IO size for fio jobs.
_nvme_calc_io_size() returns the jobs size for _run_fio_verify_io()
function. Reduce the max size of the job by one megabyte to make the
test more robust not to run out of space by accident. Note these fio
calls run with just one jobs.
_nvme_calc_run_io_size() returns the jobs size for _run_fio_rand_io()
function. Again, the jobs size is not maxing out the space and most
important it takes the number of jobs into account which are
created (number of CPUs).
