hw/intc/arm_gicv3_its: Don't clear GITS_CREADR when GITS_CTLR.ENABLED is set
The current ITS code clears GITS_CREADR when GITS_CTLR.ENABLED is set.
This is not correct -- guest code can validly clear ENABLED and then
set it again and expect the ITS to continue processing where it left
off. Remove the erroneous assignment.
