tty: ldsic: fix tty_ldisc_autoload sysctl's proc_handler
Commit 7c0cca7c847e ("tty: ldisc: add sysctl to prevent autoloading of
ldiscs") introduces the tty_ldisc_autoload sysctl with the wrong
proc_handler. .extra1 and .extra2 parameters are set to avoid other values
thant SYSCTL_ZERO or SYSCTL_ONE to be set but proc_dointvec do not uses
them.
This commit fixes this by using proc_dointvec_minmax instead of
proc_dointvec.
