printk: Fix incorrect __user type in proc_dointvec_minmax_sysadmin()
The move of proc_dointvec_minmax_sysadmin() from kernel/sysctl.c to
kernel/printk/sysctl.c introduced an incorrect __user attribute to the
buffer argument. I spotted this change in [1] as well as the kernel
test robot. Revert this change to please sparse:
kernel/printk/sysctl.c:20:51: warning: incorrect type in argument 3 (different address spaces)
kernel/printk/sysctl.c:20:51: expected void *
kernel/printk/sysctl.c:20:51: got void [noderef] __user *buffer
Fixes: faaa357a55e0 ("printk: move printk sysctl to printk/sysctl.c")
