[PATCH blktests v1 1/2] nvme/rc: add reconnect-delay argument only for fabrics transports

[Daniel Wagner <dwagner@suse.de>]

The loop transport is also considered a fabric transport. But not
connect options are supported, in particular the reconnect-delay option.

nvme-cli can't figure this out as the kernel reports the option support
for all transports (union). Thus, we have to filter out this option for
this loop transport in blktests.
