[PUSHED/OBVIOUS] Make extern declaration of dwarf_always_disassemble correct

["Christian Biesinger via gdb-patches" <gdb-patches@sourceware.org>]

This was an oversight in 491144b5e21bbfd41969c175aebb663976f59058;
dwarf2loc.c has an extern definition for dwarf_always_disassemble
that I missed. This patch updates it from int to bool to match
the definition in dwarf2read.c.

gdb/ChangeLog:

2019-09-18  Christian Biesinger  <cbiesinger@google.com>

	* dwarf2loc.c: Change extern declaration of dwarf_always_disassemble
	to bool to match definition in dwarf2read.c.
