Convert tx_qp from a single contiguous array allocation to per-queue individual allocations. Each mana_tx_qp struct is approximately 35KB. With many queues (e.g., 32/64), the flat array requires a single contiguous allocation that can fail under memory fragmentation. Change mana_tx_qp *tx_qp to mana_tx_qp **tx_qp (array of pointers), allocating each queue's mana_tx_qp individually via kvzalloc. This reduces each allocation to ~35KB and provides vmalloc fallback, avoiding allocation failure due to fragmentation.
