DB/Misc: Fix gossip condition which was never met

Fix condition for gossip option 'Lend me a Windrider.  I'm going to Spinebreaker Post!' on Wing Commander Brack for when player has got quest http://www.wowhead.com/quest=10242/spinebreaker-post.

The existing condition quest taken (9) was never met as this quest is complete in players log as soon as taken, ie just turn in no other objectives, and even when player had quest in log gossip would never be displayed,
