Kernel: Suppress logging during kmalloc heap expansion

Browse source 
The system is extremely sensitive to heap allocations during heap
expansion. This was causing frequent OOM panics under various loads.

Work around the issue for now by putting the logging behind
KMALLOC_DEBUG. Ideally dmesgln() & friends would not reqiure any
heap allocations, but we're not there right now.

Fixes #5724.
