Robin Getz af4c366cb7 PlutoSDR: Guard against null buddy shared pointers | Fix #2779

Add defensive null checks before dereferencing DeviceAPI::getBuddySharedPtr()
in the PlutoSDR input and output plugins.

DeviceAPI initializes the buddy shared pointer to nullptr, so a buddy may
exist before its shared state has been attached. This could result in null
pointer dereferences during device initialization, buddy thread
suspend/resume, or settings application.

Changes include:
- Validate buddy shared pointer in openDevice() and fail gracefully if absent.
- Guard suspendBuddies() and resumeBuddies() against null shared pointers.
- Skip buddies without shared state during applySettings() while logging a
  warning.
- Prevent dereferencing null buddy shared pointers when restarting buddy
  threads.

These changes improve robustness during PlutoSDR buddy initialization and
avoid crashes caused by partially initialized buddy relationships.
