core: mm: zero initialize phys_mem pool instances

Ensure phys_mem pool instance structure is zero initialized when created. This change fixes an issue where phys_mem pool max_allocated field may contain a fuzzy value. Fixes: c596d83 ("core: add phys_mem allocation functions") Signed-off-by: Etienne Carriere <[email protected]>
