lightnvm: refactor phys addrs type to u64
For cases where CONFIG_LBDAF is not set. The struct ppa_addr exceeds its type on 32 bit architectures. ppa_addr requires a 64bit integer to hold the generic ppa format. We therefore refactor it to u64 and replaces the sector_t usages with u64 for physical addresses. Signed-off-by: Matias Bjørling <m@bjorling.me> Signed-off-by: Jens Axboe <axboe@fb.com>
