v2.1.2

We had to revert a patch which caused sever regressions for nvme over fabrics setups, hence a v2.1.2.
While at also fix yet another fallout with the wrapper logic.

Relevant changes:

• Revert "udev: re-read the discovery log page when a discovery controller reconnected"
• wrapper: Call library version of nvme_init_copy_range_f1
