[PATCH 2/2] orangefs: fix double-unlock issue in service_operation().

[wu000273]

From: Qiushi Wu <wu000...@umn.edu>

spin_unlock(&op->lock) is called before calling wake_up_interruptible().
But spin_unlock() was called again after a call of the function
"wait_for_matching_downcall" failed. Fix this issue by remove
the second spin_unlock().
