    inode: Always fetch first entry from the inode lists during inode_table_destroy
    In inode_table_destroy, we iterate through lru and active lists
    to move the entries to purge list so that they can be destroyed
    during inode_table_prune.
    But if used "list_for_each_entry" or "list_for_each_entry_safe"
    to iterate, we could end up accessing the entries which may have
    got moved to different(purge) lists in the process and can result
    in either infinite loop or crash. The safe approach seems to fetch
    the first entry of the list in each iteration till it gets empty.
