netinet*: variable cleanup

Description

netinet*: variable cleanup

In preparation for another change factor out various variable cleanups.
These mainly include:
(1) do not assign values to variables during declaration: this makes

the code more readable and does allow for better grouping of
variable declarations,

(2) do not assign values to variables before need; e.g., if a variable

is only used in the 2nd half of a function and we have multiple
return paths before that, then do not set it before it is needed, and

(3) try to avoid assigning the same value multiple times.
