Fix AttributeError in warn_about_older_operating_systems when device_state is not yet set

Problem

When running objection -N -h <host> -n "<app>" start (network/remote connection), the following error occurs:

AttributeError: 'DeviceState' object has no attribute 'platform'

warn_about_older_operating_systems() is invoked from the start command before device_state.platform and device_state.version are populated. DeviceState does not initialize these in __init__; they are set later via set_platform() / set_version(). When connecting to a remote frida-server, the state may not be ready at the time the warning runs.

Solution

• Use getattr(device_state, 'platform', None) and getattr(device_state, 'version', None) to safely read attributes.
• Return early when either is None, skipping the Android/iOS version warnings until device state is available.
• Use the local platform and version variables in the conditionals and format strings to avoid repeated attribute access.

Testing

• Reproduced with: objection -N -h 127.0.0.1 -n "Iru Access" start
• After the fix, the session starts without AttributeError and the REPL works as expected.
