fast-import: Fix an gcc -Wuninitialized warning

Commit cbfd5e1c ("drop some obsolete "x = x" compiler warning hacks",
21-03-2013) removed a gcc hack that suppressed an "might be used
uninitialized" warning issued by older versions of gcc.

However, commit 3aa99df8 ('fast-import: clarify "inline" logic in
file_change_m', 21-03-2013) addresses an (almost) identical issue
(with very similar code), but includes additional code in it's
resolution. The solution used by this commit, unlike that used by
commit cbfd5e1c, also suppresses the -Wuninitialized warning on
older versions of gcc.

In order to suppress the warning (against the 'oe' symbol) in the
note_change_n() function, we adopt the same solution used by commit
3aa99df8.
