blktap2: fix gap in tapdisk2 disk_type numbering

Make the DISK_TYPE_* id numbering in tapdisk-disktypes.h contiguous.
Currently, id 8 is unallocated causing a null disk type entry in
tapdisk_disk_drivers array in tapdisk-disktypes.c. This causes the
function tapdisk_disktype_find() to return an error on encountering
disk types >7 (remus:, log:, etc.).
