x86: Further simplify mp_irq info handling

Browse source

assign_to_mp_irq() is copying the struct mpc_intsrc members one by
one. That's silly. Use memcpy() and let the compiler figure it out.
Same for the identical function assign_to_mpc_intsrc()

mp_irq_mpc_intsrc_cmp() is comparing the struct members one by one,
but no caller ever checks the different return codes. Use memcmp()
instead.

Remove the extra printk in MP_ioapic_info()
