hvc_console: Fix free_irq in spinlocked section
commit 611e097d7707741a336a0677d9d69bec40f29f3d
Author: Christian Borntraeger <borntraeger@de.ibm.com>
hvc_console: rework setup to replace irq functions with callbacks
introduced a spinlock recursion problem. The notifier_del is
called with a lock held, and in turns calls free_irq which then
complains when manipulating procfs. This fixes it by moving the
call to the notifier to outside of the locked section.
