I faced failure of sadump phys_base calculation and found a bug in
cache.c causes it. Due to the bug, cache_alloc() returns NULL forever
throughout execution. The fix is the 2nd patch. During the
investigation I also found a lack of malloc() allocation failure
check. The fix is the 1st patch. Primary is the 2nd one.

I built this patch set on top of devel branch.

      cache: allocate buffers at initialization to detect malloc() failure
      cache: reuse entry in pending list
