Subject: [FIB]: Avoid using static variables without proper locking

fib_trie_seq_show() uses two helper functions, rtn_scope() and 
rtn_type() that can
write to static storage without locking.

Just pass to them a temporary buffer to avoid potential  corruption
(probably not triggerable but still...)
