SELinux: remove unused av.decided field
It appears there was an intention to have the security server only decide certain permissions and leave other for later as some sort of a portential performance win. We are currently always deciding all 32 bits of permissions and this is a useless couple of branches and wasted space. This patch completely drops the av.decided concept. This in a 17% reduction in the time spent in avc_has_perm_noaudit based on oprofile sampling of a tbench benchmark.
