[PATCH] CRIS: local_irq_disable() is redundant after local_irq_save()

arch/cris/arch-v10/kernel/time.c::get_ns_in_jiffie() contains
local_irq_disable() call after local_irq_save().  This looks redundant.

arch/cris/kernel/time.c::do_gettimeofday() contains local_irq_disable() call
after local_irq_save().  This looks redundant.
