cpuset doesn't seem to be so const

This fixes a warning on last -tip:

kernel/cpuset.c: Dans la fonction «scan_for_empty_cpusets» :
kernel/cpuset.c:1932: attention : passing argument 1 of «list_add_tail» discards qualifiers from pointer target type

Actually the struct cpuset *root passed in parameter to scan_for_empty_cpusets is not supposed to be const since an entry is added on the tail of its list. Just correct the qualifier.

applied to tip/sched/cpusets, thanks Frederic!
