sysctl: Check range in do_proc_ulong_conv_ms_jiffies

Browse Source 
Add the range check back to do_proc_ulong_conv_ms_jiffies that commit
b96b5c6708 ("sysctl: Replace do_proc_do{int,ulong,uint}vec with
do_proc_vec") incorrectly removed. Append "_minmax" to the end of
do_proc_ulong_conv_ms_jiffies so it is clear that there should be a
range check.

Fixes: b96b5c6708 ("sysctl: Replace do_proc_do{int,ulong,uint}vec with do_proc_vec")
