iio:core: Handle error when mask type is not separate

When event spec is shared by multiple channels, which has definition
for mask_shared_by_type, iio_device_register_eventset fails.

For example:
static const struct iio_event_spec iio_dummy_events[] = {
{
.type = IIO_EV_TYPE_THRESH,
.dir = IIO_EV_DIR_RISING,
.mask_separate = BIT(IIO_EV_INFO_ENABLE),
.mask_shared_by_type = BIT(IIO_EV_INFO_VALUE),
}, {
.type = IIO_EV_TYPE_THRESH,
.dir = IIO_EV_DIR_FALLING,
.mask_separate = BIT(IIO_EV_INFO_ENABLE),a
.mask_shared_by_type = BIT(IIO_EV_INFO_VALUE),
}
};

If two channels use this event spec, this will result in error.

This change handles EBUSY error similar to iio_device_add_info_mask_type().
