net: mana: Use kvmalloc for large RX queue and buffer allocations

Browse source

The RX path allocations for rxbufs_pre, das_pre, and rxq scale with
queue count and queue depth. With high queue counts and depth, these can
exceed what kmalloc can reliably provide from physically contiguous
memory under fragmentation.

Switch these from kmalloc to kvmalloc variants so the allocator
transparently falls back to vmalloc when contiguous memory is scarce,
and update the corresponding frees to kvfree.
