Bug#58221 : mysqladmin --sleep=x --count=x keeps looping

When mysqldadmin is run with sleep and count options,
it goes into an infinite loop and keeps executing the
specified command.

This happened because the statement, responsible for
decrementing the count value, was missing.

Fixed by adding a statement which will decrement the
count value for each iteration.
