Annotate unused parameters on inline definitions as such

Browse Source 
* libspl: umem: These are obviously and intentionally unused; annotate 
  them as such to appease -Wunused-parameter builds that include this 
  header.

* sys/dmu.h: In this case, clear_on_evict_dbufp is only used for 
  ZFS_DEBUG builds, so annotate it as __maybe_unused to appease 
  -Wunused-parameter.
