_damo_fs: Remove write_files()

write_files() was designed for handling multiple file i/o operations
that supposed to all success.  It is convenient and useful, but makes it
complicated to handle failures in the middle of the operations.  Now all
_damo_fs users are using write_file() instead.  Remove the function that
not really being used.

-operations can be either {path: content}, or [operations].  In the former case,
-this function writes content to path, for all path/content pairs in the
-dictionary.  In the latter case, operations in the list is executed
-sequentially.  If the path is for a file, content should be a string.  If the
-path is for a directory, the content should be yet another operations.  In the
-latter case, upper-level path is prefixed to paths of the lower-level
-operations paths.

-For example:
-    {
-        'foo': 'bar',
-        'dirA': {
-            'fileA': '123',
-            'fileB': '456',
-            },

-            {'fileA': '42'},
-            {'fileB': '4242'},
-        ]
-    }
-
-    writes 'bar' to 'foo',
-    writes '123' to 'dirA/fileA',
-    writes '456' to 'dirA/fileB', and
-    writes '42' to 'fileA' then writes '4242' to 'fileB',
-    in any order
-
-Return an error string if fails any write, or None otherwise.
