tools lib traceevent: Fix conversion of pointer to integer of different size
gcc complaint on 32-bit system: /home/acme/git/linux/tools/lib/traceevent/event-parse.c: In function ‘eval_num_arg’: /home/acme/git/linux/tools/lib/traceevent/event-parse.c:3468:9: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] This is because the eval_num_arg returns everything as an 'unsigned long long', so it converts a void pointer to a wider integer, fix it by converting the void pointer to an integer of the same size, 'unsigned long', before casting it to 'unsigned long long'.
