1. Fix ice FDIR and hash flow memory leak.
2. Fix the ice definition of LIST_FOR_EACH_ENTRY_SAFE not
   save tmp which cause list deletion incompletely.

Fixes: 5f0978e96220 ("net/ice/base: add OS specific implementation")
Fixes: f5cafa961fae ("net/ice: add flow director create and destroy")
Fixes: 5ad3db8d4bdd ("net/ice: enable advanced RSS")
