Subject: sh: Ensure IRQs are enabled across do_notify_resume().

do_notify_resume() can trigger the freezer via the try_to_freeze() path
(both explicitly through a redundant call in do_signal() or via
get_signal_to_deliver()). That IRQs were disabled across this callsite
became apparent with the might_sleep() introduction in try_to_freeze() by
Tejun in a0acae0e886d44bd5ce6d2f173c1ace0fcf0d9f6, resulting in:

	BUG: sleeping function called from invalid context at include/linux/freezer.h:45
	in_atomic(): 0, irqs_disabled(): 1, pid: 819, name: ntpd
	no locks held by ntpd/819.
	Stack: (0x9c81be80 to 0x9c81c000)
	...

Subject: sh: Remove redundant try_to_freeze() invocations.

get_signal_to_deliver() takes care of this, kill off the redundancies, as
per the avr32 change.
