cxgbi_alloc_big_mem allocates large chunks of memory, and can occasionally
request amounts from kmalloc that exceed the allocators capacity. This
typically leads to a stack trace from the zoned buddy allocator in the message
log. But if kmalloc fails, cxgbi_alloc_big_mem backs off and uses vmalloc
instead. Given that, and the fact that the two calls sites have their own error
messages if both kmalloc and vmalloc fail, I think the stack trace printing
isn't really needed.
Modify the call to kmalloc to pass __GFP_NOWARN in as well, so that internal
kmalloc warnings are suppressed.
