net/ice/base: change misc ACL style

This is a collection of minor ACL style changes including:

- When there is nothing to unroll, return a value directly.
- Return ICE_SUCCESS(0) in cases where an error was previously checked
  so ICE_SUCCESS is the only possible return.
- Remove unnecessary parentheses and newlines
- Move unroll of allocation to end of function and use goto on errors to
  free.
- Fix function header comment style
- Remove 'else' from an 'if else' condition where both conditions return
  a value to reduce indentation.
