nvme-pci: set min_align_mask before calculating max_hw_sectors
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.
