destroy the partitioning system's on-disk structure. * Adjusted the existing partitioning system implementations accordingly. Actually implemented the hook for the intel partitioning system. * Added Uninitialize() method to KDiskSystem and KPartitioningSystem. The latter implements the method calling the new module hook. * _user_uninitialize_partition(): Also let the disk system uninitialize the on-disk structure. This fixes the failure to initialize a disk device with BFS, when it contains a valid partition map with at least one partition. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42140 a95241bf-73f2-0310-859d-f6bbb57e9c96
