kernel.h: add pr_warn for symmetry to dev_warn, netdev_warn 

The current logging macros are
pr_<level>, dev_<level>, netdev_<level>, and netif_<level>.
pr_ uses warning, the other use warn.

Standardize these logging macros a bit more by adding pr_warn and
pr_warn_ratelimited.

Right now, there are:

$ for level in emerg alert crit err warn warning notice info ; do \
    for prefix in pr dev netdev netif ; do \
      echo -n "${prefix}_${level}:	`git grep -w "${prefix}_${level}" | wc -l`	" ; \
    done ; \
    echo ; \
  done
