Fix code that handles KVM_SET_ONE_REG, KVM_GET_ONE_REG ioctls to work in BE image. Before this fix get/set_one_reg functions worked correctly only in LE case - reg_from_user was taking 'void *' kernel address that actually could be target/source memory of either 4 bytes size or 8 bytes size, and code copied from/to user memory that could hold either 4 bytes register, 8 byte register or pair of 4 bytes registers. In order to work in endian agnostic way reg_from_user to reg_to_user functions should copy register value only to kernel variable with size that matches register size. In few place where size mismatch existed fix issue on macro caller side.
