ext2fs: fix error handling in ext2fs_add_dir_block

In ext2fs_add_dir_block() the dblist allocation size was changed to
grow as the number of items in the dblist increases.  However, the
error handling in case of allocation failure wasn't changed to match.

Fix the error case to revert to the old allocation size on failure.
