selftests: ublk: correct last_rw map type in seq_io.bt
The last_rw map is initialized with a value of 0 but later assigned the
value args.sector + args.nr_sector, which has type sector_t = u64.
bpftrace complains about the type mismatch between int64 and uint64:
trace/seq_io.bt:18:3-59: ERROR: Type mismatch for @last_rw: trying to assign value of type 'uint64' when map already contains a value of type 'int64'
@last_rw[$dev, str($2)] = (args.sector + args.nr_sector);
Cast the initial value to uint64 so bpftrace will load the program.
