tc_util: Drop needless pointer check

Browse Source 
The function parse_action_control_slash() returns early if 'p' is NULL,
so after the first call to action_a2n(), 'p' is guaranteed not to be
NULL. Otherwise, the assignment '*p = 0' above would dereference the
NULL pointer already anyway, so just drop this check here.
