Fix current_uiout restore in mi_load_progress

[Joseph S. Myers]

I observed a problem where GDB segfaulted in MI testing while the test
program was being loaded onto the target, which I traced to
mi_load_progress failing to restore the current_uiout global on exit -
instead assigning to the local uiout variable.  This appears to be an
oversight in Pedro's 2011-08-04 patch renaming the former uiout
global.

This patch fixes this in the obvious way.  Approved offlist by Pedro
and committed.

	* mi/mi-main.c (mi_load_progress): Restore saved_uiout value to
	current_uiout, not uiout.
