[PATCH] Revert "md: fix a crash in mempool_free"

[uli]

From: Ulrich Hecht <uli@kernel.org>

This reverts commit a8e2077ebc799a5fc55c369d4a4e41ba05534fb6, which is
commit cf06b162f5b6337b688072a1a47941280b8f7110 upstream.

The patch has been applied twice:

779785788a82f md: fix a crash in mempool_free
a8e2077ebc799 md: fix a crash in mempool_free

This reverts the second variant which has been mangled and causes a crash
when using raid1.

Alexander, could you do us the favor of testing this again to make sure that
the removal of the rdev_dec_pending() call doesn't cause any issues? Thanks.
