libcamera: raspberry: Fix segfault in ~RPiCameraData()
The RPiCameraData class destructor tries to stop its ipa_ instance
without making sure it has been initialized.
If the RPiCameraData gets destroyed before its ipa_ member is
initialized, for example if the sensor initialization fails during the
match() function, a nullptr dereference segfault is triggered preventing
a graceful library teardown.
Fix this by checking for ipa_ to be initialized before stopping it.
