qmempool: function order in qmempool.c

Adjust the order of the functions, as __qmempool_alloc_from_sharedq()
is calling __qmempool_alloc_from_slab() is should appear first.

qmempool: unexport the *_slab functions

Its now not necessary to export:
 __qmempool_alloc_from_slab()
 __qmempool_free_to_slab().

As they are now only called from qmempool.c.

Be carefull not to define them as static, as this will cause them to
get inlined, which hurts icache usage, as they should not be called
very often we don't want them inlined.
