[NET]: Undo code bloat in hot paths due to print_mac().

If print_mac() is used inside of a pr_debug() the compiler
can't see that the call is redundant so still performs it
even of pr_debug() ends up being a nop.

So don't use print_mac() in such cases in hot code paths,
use MAC_FMT et al. instead.

As noted by Joe Perches, pr_debug() could be modified to
handle this better, but that is a change to an interface
used by the entire kernel and thus needs to be validated
carefully.  This here is thus the less risky fix for
2.6.25
