nvmecontrol: Display additional Fabrics-related fields for cdata

Browse source 
Some of these fields are specific to Fabrics controllers (such as the
size of capsules) while other fields are shared with PCI-e
controllers, but are more relevant for Fabrics controllers (such as
KeepAlive timer properties).
