hfs: Replace BUG_ON with error handling for CNID count checks
In a06ec283e125 next_id, folder_count, and file_count in the super block
info were expanded to 64 bits, and BUG_ONs were added to detect
overflow. This triggered an error reported by syzbot: if the MDB is
corrupted, the BUG_ON is triggered. This patch replaces this mechanism
with proper error handling and resolves the syzbot reported bug.
