elfcompress: remove redundant assignment

At the point of "Nothing to do" fnew variable has not been assigned
after initialization, so it does not have to be reset to NULL.

Note that any reset of fnew to NULL has to preceded with free(fnew).

Fixes: ed62996def ("elfcompress: Don't rewrite file if no section data needs to be updated.")
