tools/vm/slabinfo: use alphabetic order when two values are equal
When the number of partial slabs in each cache is the same (e.g., the value are 0), the results of the `slabinfo -X -N5` and `slabinfo -P -N5` are different. / # slabinfo -X -N5 ... Slabs sorted by number of partial slabs --------------------------------------- Name Objects Objsize Space Slabs/Part/Cpu O/S O %Fr %Ef Flg inode_cache 15180 392 6217728 758/0/1 20 1 0 95 a kernfs_node_cache 22494 88 2002944 488/0/1 46 0 0 98 shmem_inode_cache 663 464 319488 38/0/1 17 1 0 96 biovec-max 50 3072 163840 4/0/1 10 3 0 93 A dentry 19050 136 2600960 633/0/2 30 0 0 99 a / # slabinfo -P -N5 Name Objects Objsize Space Slabs/Part/Cpu O/S O %Fr %Ef Flg bdev_cache 32 984 32.7K 1/0/1 16 2 0 96 Aa ext4_inode_cache 42 752 32.7K 1/0/1 21 2 0 96 a dentry 19050 136 2.6M 633/0/2 30 0 0 99 a TCPv6 17 1840 32.7K 0/0/1 17 3 0 95 A RAWv6 18 856 16.3K 0/0/1 18 2 0 94 A This problem is caused by the sort_slabs(). So let's use alphabetic order when two values are equal in the sort_slabs(). By the way, the content of the `slabinfo -h` is not aligned because the `-P|--partial Sort by number of partial slabs` uses tabs instead of spaces. So let's use spaces instead of tabs to fix it.
