[PATCH 3/4] windows-nat: Consistently use numeric get_context parameter to thread_rec()

[Jon Turney <jon dot turney at dronecode dot org dot uk>]

thread_rec()'s get_context parameter is not a bool, and has the following
meanings

>0  suspend, retrieve context
0   use already retrieved context
<0  already suspended, retrieve context

Consistently use numeric values throughout windows-nat.c, rather than a mixture
of numeric and bool values.

gdb/ChangeLog:

2015-06-03  Jon Turney  <jon.turney@dronecode.org.uk>

	* windows-nat.c : Consistently use numeric get_context parameter
	to thread_rec() throughout.
