udc: Fix recursive spinlocks
Driver had recursive spinlock locking: 1. jz4740_queue() acquires lock 2. done() is called in chain: jz4740_queue()->jz4740_ep0_kick()->jz4740_ep0_in()->write_fifo_ep0()->done() and it tries to acquire same lock. 3. Deadlock. Signed-off-by: Yauhen Kharuzhy <jekhor@gmail.com> SVN-Revision: 21619
