Johan Hovold 41e5d9cef3 lib/genalloc: fix device leak in of_gen_pool_get() 
commit 1260cbcffa upstream.

Make sure to drop the reference taken when looking up the genpool platform
device in of_gen_pool_get() before returning the pool.

Note that holding a reference to a device does typically not prevent its
devres managed resources from being released so there is no point in
keeping the reference.

Fixes: 9375db07ad ("genalloc: add devres support, allow to find a managed pool by device")
