Reviewed by Philippe Normand and Chris Dumez.
AudioDestinationNode::renderQuantum() runs the audio thread inside a
ForbidMallocUseForCurrentThreadScope, which extends through
handlePostRenderTasks() and the node-deletion bookkeeping it performs. The
fallback in AudioNodeInput::disconnect() calls m_disabledOutputs.remove()
without a DisableMallocRestrictionsForCurrentThreadScope; HashSet::remove()
may shrink and rehash, allocating, and trips the assertion.
AudioSummingJunction::removeOutput() and AudioNodeInput::disable() / enable()
already wrap their hash-set mutations the same way; do the same for the
disabled-list fallback in disconnect().
