Fix a few places where an extra cache inode LRU reference was taken

cache_inode_create, cache_inode_lookup, and cache_inode_lookupp both return a
reference to the resulting entry, and that reference can be handed off to
data->current_entry.

Use cache_inode_get_lru_ref_pinned to correctly get LRU reference

Given an object with a cache entry pointer, we can not just simply get
an LRU reference, we must use cache_inode_get_lru_ref_pinned to assure
the entry is not dead before taking a reference.

In most cases, if the entry is dead, we continue to loop looking for
objects and their associated entries, assuming that eventually the
objects for the dead entry will be removed.
