Lin Yujun 03410e8756 hexagon: Fix unbalanced spinlock in die()
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.
