module: remove use of uninitialized variable len

Browse Source 
clang build reports
kernel/module/stats.c:307:34: error: variable
  'len' is uninitialized when used here [-Werror,-Wuninitialized]
        len = scnprintf(buf + 0, size - len,
                                        ^~~
At the start of this sequence, neither the '+ 0', nor the '- len' are needed.
So remove them and fix using 'len' uninitalized.
