If swiotlb is force enabled dma_max_mapping_size ends up calling
swiotlb_max_mapping_size which takes into account the min align
mask for the device.
Set the min align mask for nvme driver before calling
dma_max_mapping_size while calculating max hw sectors.
Fixes: 7637de311bd2 ("nvme-pci: limit max_hw_sectors based on the DMA max
mapping size")
