[Patch] mi-var-display regression failures fix

["Marc Khouzam" <marc.khouzam@ericsson.com>]

Hi,

There are a couple of new unexpected failures in MI regressions.
I believe that an xfail marker was removed by mistake, which makes a couple of tests seem to fail.

Instead of putting back the xfail, I thought that fixing the error may be even better :-)
This patch fixes those two testcases by having the test program run until variable are initialized.

BTW, you should have my Copyright Assignment on file now, and my sourceforge account is setup, 
so I can commit this if I get approval.

Thanks

	* gdb.mi/mi-var-display.exp: Stop at end of do_special_tests
	instead of beginning to make an extra test pass.
	* gdb.mi/mi2-var-display.exp: Likewise.
