Some functions's comments were not entirely correct on stap-probe.c,
so this patch updates them.

Pushed as obvious.

2019-05-16  Sergio Durigan Junior  <sergiodj@redhat.com>

	* stap-probe.c (stap_get_opcode): Update comment.
	(stap_get_expected_argument_type): Likewise.
	(handle_stap_probe): Likewise.
