nvme-pci: use the same attributes when freeing host_mem_desc_bufs.
[ Upstream commit cc667f6d5de023ee131e96bb88e5cddca23272bd ]
When using HMB the PCIe host driver allocates host_mem_desc_bufs using
dma_alloc_attrs() but frees them using dma_free_coherent(). Use the
correct dma_free_attrs() function to free the buffers.
