This patch moves the check for deprecated_query_hook before 
input-not-from-terminal check in defaulted_query, instead of after it. 
Presently, the only thing that uses deprecated_query_hook is the MI 
backend, which uses it to suppress the question entirely, so that the 
current behavior leads to the situation where nothing is printed when 
the input is a terminal but there is a message otherwise, which is 
somewhat odd.

The specific problem this patch solves is a testing issue with 
gdbserver.  mi_gdb_target_load says:

mi_gdb_test "kill" ".*" ""

and if the test harness is not running GDB from a terminal we get:

Expecting: ^(kill[
]+)?(.*[
]+[(]gdb[)]
[ ]*)
kill
&"kill\n"
~"Kill the program being debugged? (y or n) [answered Y; input not from 
terminal]\n"
ERROR: Got interactive prompt.

because it is tripping over the "\\(y or n\\) " pattern in mi_gdb_test. 
  Of course mi_gdb_test could be fixed to recognize the "input not from 
terminal" message as valid, but I don't think that's the intended MI 
behavior.  I think this is a bug in GDB, not the testsuite.

OK to commit?
