Jianxiong Gao 2fa0387fa2 nvme-pci: set min_align_mask
commit: 3d2d861eb03e8ee96dc430a54361c900cbe28afd

The PRP addressing scheme requires all PRP entries except for the
first one to have a zero offset into the NVMe controller pages (which
can be different from the Linux PAGE_SIZE).  Use the min_align_mask
device parameter to ensure that swiotlb does not change the address
of the buffer modulo the device page size to ensure that the PRPs
won't be malformed.
