Description

Describe the bug
Spatial transforms won't apply in lazy mode, as explained in another previous issue that was closed

To Reproduce

import matplotlib.pyplot
import monai.transforms
from torchvision.transforms import Compose
x = np.zeros((1,100,100,100))
x[0, 30:50, 40:70, 10:80] = 1
plt.imshow(
    x[0, ...].max(0)
)
plt.show()
t = Compose([
    monai.transforms.RandRotate(range_x=0.52, prob=1.0, lazy=True),
    monai.transforms.ApplyPending(),
])
for _ in range(5):
    plt.imshow(
        t(x).numpy()[0, ...].max(0)
    )
    plt.show()

Expected behavior
If i'm correct, ApplyPending should have applied the lazy transforms
