Fix dangling-reference warnings for particle functions. (AMReX-Codes#…

…4241)

## Summary

With gcc 13.2 and all warnings/errors turned on, some particle functions
generate a dangling-reference error.
This PR fixes those errors.

## Additional background

To reproduce, in `Tests/Particles/ParticleMesh/main.cpp` add lines
149-150:
```
myPC.IncrementWithTotal(acceleration , 0);
myPC.SortParticlesForDeposition({0,0,0});
```

and in `Tests/Particles/ParticleMesh/GNUmakefile`
add a final line:
```
CXXFLAGS += -Werror -Wall -Wextra
```

Similar lines in:
`./Src/Extern/SENSEI/AMReX_ParticleDataAdaptorI.H`
may also have the same error, but I don't have SENSEI installed to
check.

## Checklist

The proposed changes:
- [x] fix a bug or incorrect behavior in AMReX
- [ ] add new capabilities to AMReX
- [ ] changes answers in the test suite to more than roundoff level
- [ ] are likely to significantly affect the results of downstream AMReX
users
- [ ] include documentation in the code and/or rst files, if appropriate
