[PATCH 5.15 049/530] nvme-pci: set min_align_mask before calculating max_hw_sectors

[Greg Kroah-Hartman]

From: Rishabh Bhatnagar <risbhat@xxxxxxxxxx>

commit 61ce339f19fabbc3e51237148a7ef6f2270e44fa upstream.

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.
