btrfs/132: wait the writer to avoid EBUSY

Browse Source 
The kill and wait method will only wait for the children process to
exit, while the xfs_io can still run at background.

This makes the test always fails on HDD backed physical machine.

Use the "while ps aux | grep" method in btrfs/069 to truely wait the
xfs_io to finish.
