[PATCH] [OBV] gdb/rs6000: Fix maybe-uninitialized warning.

["Marcin Kościelnicki" <koriakin@0x04.net>]

Introduced by 657f9cde9d531c9929bef9e02a8064101d568f50.

gdb/ChangeLog:

	* rs6000-tdep.c (rs6000_frame_cache): Initialize frame and pc to 0
	to avoid spurious warnings.
---
Thanks for the report.  I can't reproduce the problem locally, but this
patch (pushed as obvious) should do the trick.
