mbcache: revert "fs/mbcache.c: make count_objects() more robust"
This reverts commit d5dabd6339
.
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.)
