tipc: improve function tipc_wait_for_cond()

Commit 844cf763fba6 ("tipc: make macro tipc_wait_for_cond() smp safe")
replaced finish_wait() with remove_wait_queue() but still used
prepare_to_wait(). This causes unnecessary conditional
checking  before adding to wait queue in prepare_to_wait().

This commit replaces prepare_to_wait() with add_wait_queue()
as the pair function with remove_wait_queue().
