examples/ioat: fix failure check for ioat dequeue

The nb_dq return value from the ioat dequeue is negative in failure
cases, however the variable was an unsigned int, causing the condition
where nb_dq <= 0 to never be true. This is now cast to a signed int,
which will successfully reflect the -1 value to be used in this
conditional check.
