Allow WaitLatch() to be used without a latch.

Due to flaws in commit 3347c982bab, using WaitLatch() without
WL_LATCH_SET could cause an assertion failure or crash.  Repair.

While here, also add a check that the latch we're switching to belongs
to this backend, when changing from one latch to another.
