test/ocf: Don't depend on gen_nvme.sh while detecting nvme ctrls

Browse Source 
gen_nvme.sh requires that all the nvme devices are not bound to the
nvme driver which doesn't have to be the case when clear_nvme() is
called. To not depend on which driver is in use, simply iterate over
pci bus to find a proper device. This avoids additional setup.sh
ping-pong which is required to make use of gen_nvme.sh.

Additionally, upon exiting, in case mounts for given nvme device were
detected, keep the test environment reset to leave nvmes bound to the
nvme driver.
