sysctl: fix maybe-uninitialized warnings
kernel/sysctl.c: In function '__do_proc_dointvec.isra.3':
kernel/sysctl.c:2030:8: warning: 'kbuf' may be used uninitialized in this function [-Wmaybe-uninitialized]
char *tmp = skip_spaces(*buf);
^~~
kernel/sysctl.c:2183:8: note: 'kbuf' was declared here
char *kbuf;
^~~~

char *tmp = skip_spaces(*buf);

This will be initialized to NULL normally.
