Lin Yujun 2ac1d4705b hexagon: Fix unbalanced spinlock in die() 
[ Upstream commit 03410e87563a122075c3721acc7d5510e41d8332 ]

die executes holding the spinlock of &die.lock and unlock
it after printing the oops message.
However in the code if the notify_die() returns NOTIFY_STOP
, die() exit with returning 1 but never unlocked the spinlock.

Fix this by adding spin_unlock_irq(&die.lock) before returning.

Fixes: cf9750bae2 ("Hexagon: Provide basic debugging and system trap support.")
