LU-1895 tests: don't fail mmp test_5 due to race
In the mmp.sh test_5() mount_after_unmount() testing, it is possible
that the first filesystem unmounts successfully before the second
one starts, and there is no contention for the MMP block.
This caused the test to fail on a regular basis. However, there is
still value in running this test, since non-MMP race conditions have
previously been seen in this area (OBD device refcount, etc).
Make mount_after_unmount() more robust, only failing if the first
filesystem is still mounted at the same time as the second one.
