scripts/fio-wrapper: Simplify check for bdev devices

Browse Source 
While testing fedora35 under 5.18 kernel it was noticed that the
sysfs dir structure changed comparing to older versions of the
kernel. To make sure proper devices can be found regardless of
the kernel version simplify the process by just looking up
the model of the ctrl given nvme block device is connected to.
