CLEANUP: cli: make "show fd" use a const connection to access other fields

Browse Source 
Over time the code has uglified, casting fdt.owner as a struct connection
for about everything. Let's have a const struct connection* there and take
this opportunity for passing all fields as const as well.

Additionally a misplaced closing parenthesis on the output was fixed.
