[BUG] Assert always fails while checking whether local buffer is dirty of is exclusively locked

Hi,
Commit 00d7fb5e2e39198387ae00af8dd18b787b6a4d63 adds
BufferIsExclusiveLocked and BufferIsDirty functions.
They take into account that they can also be called for temporary
tables, but they both have assert, that will always fail
for temporary tables :
***
Assert(LWLockHeldByMeInMode(BufferDescriptorGetContentLock(bufHdr),
LW_EXCLUSIVE));
***

They fails because LockBuffer function just skip acquiring lock for
temporary table :
***
if (BufferIsLocal(buffer))
return;
***

I suppose that fix can be done as in the attached to this email patch
(for REL_17_STABLE)
