[PATCH 16/25] lightnvm: pblk: remove pblk_gc_stop

[Matias Bjørling]

From: Hans Holmberg <hans.holmb...@cnexlabs.com>

pblk_gc_stop just sets pblk->gc->gc_active to zero, ignoring
the flush parameter. This is plain confusing, so remove the
function and set the gc active flag at the call points instead.
