nvme: lightnvm: make MLC num_pairs little endian
According to the OpenChannel SSD interface specification the NAND flash MLC page pairing information's number of page page pairings field is the first two bytes in the MLC Page Pairing data structure. The hardware's data structure itself is little endian so annotate it as such, like the rest of lighnvm's data structures.
