A later commit will add a struct irq_work member to struct task_struct, which
would require <linux/sched.h> to include the definition of struct
irq_work.
Thanks to header dependency hell, incudling <linux/irq_work.h> in <linux/sched.h>
results in defining inline helpers using not-yet-defined fields (mm_struct,
task_struct, various task states...).
Break off the definition of struct irq_work into its own header file.
