John Baldwin 686b1e6bc0 Small style fixes:
- Avoid side-effect assignments in if statements when possible.
- Don't use ! to check for NULL pointers, explicitly check against NULL.
- Explicitly check error return values against 0.
- Don't use INTR_MPSAFE for interrupt handlers with only filters as it is
  meaningless.
- Remove unneeded function casts.
