lightnvm: refactor rqd ppa list into set/free
A device may be driven in single, double or quad plane mode. In that case, the rqd must have either one, two, or four PPAs set for a single PPA sent to the device. Refactor this logic into their own functions to be shared by program/erase/read in the core. Signed-off-by: Matias Bjørling <m@bjorling.me> Signed-off-by: Jens Axboe <axboe@fb.com>
