zram: revalidate disk under init_lock
Commit b4c5c60920e3 ("zram: avoid lockdep splat by revalidate_disk")
moved revalidate_disk call out of init_lock to avoid lockdep
false-positive splat. However, commit 08eee69fcf6b ("zram: remove
init_lock in zram_make_request") removed init_lock in IO path so there
is no worry about lockdep splat. So, let's restore it.
This patch is needed to set BDI_CAP_STABLE_WRITES atomically in next
patch.
Fixes: da9556a2367c ("zram: user per-cpu compression streams")
