Clarify what happens to match data on failure

Problem reported by Ernesto Alfonso (Bug#21279).
* doc/lispref/searching.texi (Regexp Search, Simple Match Data):
Document more carefully what happens to match data after a failed
search.
* src/search.c (Fmatch_beginning, Fmatch_end): Document that
the return value is undefined if the last search failed.
(Fmatch_data): Simplify doc string line 1.
