Bug report

Bug summary

Calling get_xaxis_transform() after set_yscale('symlog') results in a RecursionError. I found this bug when investigating why there's no yticks (except 0) shown when using a symlog scale.

Code for reproduction

from matplotlib import pyplot as plt
import numpy as np

f, ax = plt.subplots()
ax.plot(np.arange(100))
ax.set_yscale('symlog')
print(ax.get_yaxis_transform())

Actual outcome

RecursionError: Maximum recursion depth exceeded

Expected outcome
An object of type matplotlib.scale.SymmetricLogScaleTransform or something like that.
