lightnvm: reserved space calculation incorrect
The nvm_dev->max_pages_per_blk variable was removed in favor of the new nvm->sec_per_blk variable. The ->max_pages_per_blk variable was still used in rrpc_capacity, reporting the reserved capacity to zero. Replace with ->sec_per_blk to calculate the reserved area again.
