Lib.c: Fix geting devname for devices with long path

In scenario where VMD is enabled, and "x8" type of NVMe drive is
plugged into PCIe switch - the path will be longer than 200 chars
(additional VMD domain + 2 level of PCIe switches).
This patch makes the buffer big enough to handle this kind of
configurations.
