tracing: Print the bucket size as unsigned
A key's bucket size reads back negative once it exceeds LONG_MAX:
# echo 'hist:keys=next_pid.buckets=18446744073709551615' > trigger
# cat trigger
hist:keys=next_pid.buckets=-1:vals=hitcount:...
parse_field() takes the size with kstrtoul() and rejects only zero, so the
whole unsigned long range is accepted and stored, but hist_field_print()
renders it with %ld.
Print it with %lu.
