lightnvm: pblk: move ring buffer alloc/free rb init
pblk's read/write buffer currently takes a buffer and its size and uses it to create the metadata around it to use it as a ring buffer. This puts the responsibility of allocating/freeing ring buffer memory on the ring buffer user. Instead, move it inside of the ring buffer helpers (pblk-rb.c). This simplifies creation/destruction routines. Signed-off-by: Javier González <javier@cnexlabs.com> Signed-off-by: Matias Bjørling <mb@lightnvm.io> Signed-off-by: Jens Axboe <axboe@kernel.dk>
