EAL should always use rte_log instead of putting errors to
stderr (which maybe redirected to /dev/null in a daemon).

Also checks for null before rte_free are unnecessary.

Thanks - good improvements.

A few nit-picks, I'll send a v2 based on your changes here with
the below notes implemented.

I'll add my Sign-off for code changes, and Acked-by for the whole,
hope that's OK, if you'd prefer two different patches just let me know.

Added line here should really split return-value and function into
two lines. Found another instance of this, splitting that too to make
the whole file consistent.

Rest of file uses 1 line to split variable declarations and functions,
so one line will do.

Some of these "strings" can be on the same line as RTE_LOG and stay
inside the 80 char limit, moving them up a line for consistency.
