[commit/obvious] Cleanup `n_probes' in probe API

[Sergio Durigan Junior <sergiodj at redhat dot com>]

This is an obvious commit to rename the variable `n_probes' to `n_args',
since it refers to the number of arguments of a probe.

	* probe.c (probe_safe_evaluate_at_pc): Rename variable `n_probes'.
	* stap-probe.c (compile_probe_arg): Likewise.
