Android-backend: fix for setting maximumZoomFactor

Before this commit, the maximum zoom factor was set locally in the
QAndroidCamera class. It was not propagated to its base QPlatformCamera
class. That cause the problem with wrong value returned by
maxZoomFactor() method.

This commit contains setting correctly m_maxZoom in QPlatformCamera and
remove not needed m_maximumZoom member from QAndroidCamera.

Fixes: QTBUG-105372
Pick-to: 6.5 6.2
