[03/25] lightnvm: use internal pblk methods

Commit Message

Matias Bjørling Dec. 20, 2017, 5:21 p.m. UTC

Now that rrpc has been removed, the only users of the ppa helpers
is pblk. However, pblk already defines similar functions.

Switch pblk to use the internal ones, and remove the generic ppa
helpers.
