Subject: builtin/diff.c: remove duplicated call to diff_result_code()

The return value from builtin_diff_files() is fed to diff_result_code()
by the caller, and all other callees like builtin_diff_index() do not
have their own call to diff_result_code().  Remove the duplicated one
from builtin_diff_files() and let the caller handle it.
