[PATCH] Function btree_get_extent: Incorrect if-else if statement

[André Nogueira]

The btree_get_extent function (in file disk-io.c) calls the
add_extent_mapping (in file extent_map.c). The add_extent_mapping
function can return two values: 0 or -EEXIST.

After the call, it is used an if-else if statement. If the result is
-EEXIST, the if statement is executed. If the result is 0, the else if
statement will not be executed because it is false.

Thank you.
