mbcache: revert "fs/mbcache.c: make count_objects() more robust"
This reverts commit d5dabd633922ac5ee5bcc67748f7defb8b211469. This patch did absolutely nothing, because ->c_entry_count is unsigned. In addition if there is a bug in how mbcache maintains its entry count, it needs to be fixed, not just hacked around. (There is no obvious bug, though.)
