sysctl: min/max bounds are optional
sysctl check complains with a WARN() when proc_doulongvec_minmax() or
proc_doulongvec_ms_jiffies_minmax() are used by a vector of longs (with
more than one element), with no min or max value specified.
This is unexpected, given we had a bug on this min/max handling :)
