[PATCH] gdb.mi/mi-nsintrall.exp: fix racy tests (PR testsuite/12649)

[Marek Polacek <mpolacek at redhat dot com>]

The troublemakers here were two gdb_test_multiple tests.  Thus, I've
converted them into the mi_gdb_test.  OK?

2011-06-20  Marek Polacek  <mpolacek@redhat.com>

        * gdb.mi/mi-nsintrall.exp: Replace gdb_test_multiple with mi_gdb_test.
