tipc: Relocate trivial link status functions to header file
Rather than live in link.c where they can only be used in that file alone,
these helper routines are better served by being in link.h
Relocated are the following:
link_working_working
link_working_unknown
link_reset_unknown
link_reset_reset
link_blocked
link_congested
