scripts/coccinelle: more cleanup of int literal to timeout

Sort the functions within the regular expression so they can be
checked more easily.

Remove k_thread_deadline_set as it takes an argument in cycles.  (The
one in-tree call to this function was not affected by this error.)

Add missed k_mbox_data_block_get.

Fix an overly ambitious multi-match disjunct that covered some
non-existent functions.
