exec.c, compat.c: fix count(), compat_count() bounds checking
With MAX_ARG_STRINGS set to 0x7FFFFFFF, and being passed to 'count()' and compat_count(), it would appear that the current max bounds check of fs/exec.c:394: if(++i > max) return -E2BIG; would never trigger. Since 'i' is of type int, so values would wrap and the function would continue looping. Simple fix seems to be chaning ++i to i++ and checking for '>='.
