Subject: [PATCH] Fix memory discard + callstack.

Bug (High Severity): Wrong queue type in MemDiscardCallstack

In the callstack path of MemDiscardCallstack, the wrong queue type is
sent:

  SendMemDiscard( QueueType::MemDiscard, thread, name );

Every other callstack variant correctly uses its callstack queue type
(MemAllocCallstack, MemFreeCallstack, etc.), but this one uses the
non-callstack type. The SendMemDiscard assertion at line 1026 confirms
MemDiscardCallstack is a valid value.

Impact: The callstack captured by SendCallstackSerial() will be orphaned.
The server processes the event via the non-callstack handler, leaving the
callstack serial data unconsumed, which desynchronizes the serial queue
and corrupts all subsequent events.
