Zhen Lei 5e3a031dfa debugobjects: Fix conditions in fill_pool() 
commit 684d28feb8 upstream.

fill_pool() uses 'obj_pool_min_free' to decide whether objects should be
handed back to the kmem cache. But 'obj_pool_min_free' records the lowest
historical value of the number of objects in the object pool and not the
minimum number of objects which should be kept in the pool.

Use 'debug_objects_pool_min_level' instead, which holds the minimum number
which was scaled to the number of CPUs at boot time.

[ tglx: Massage change log ]

Fixes: d26bf5056f ("debugobjects: Reduce number of pool_lock acquisitions in fill_pool()")
Fixes: 36c4ead6f6 ("debugobjects: Add global free list and the counter")
