[PATCH] wp-replication: Fix test case loop

When executing wp-replication.exp on S/390, the loop that counts the
number of available hardware watchpoints does not terminate properly,
because *all* "watch" commands yield "hardware watchpoints".

Since the C source code is not prepared for more than NR_THREADS
hardware watchpoints anyhow, I suggest to add the appropriate exit
condition to the loop.

	* gdb.threads/wp-replication.exp: Stop counting available hardware
	watchpoints after NR_THREADS iterations.
