module: remove use of uninitialized variable len
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.
