ping: remove pr_err from ping_lookup
As Jakub noticed, prints should be avoided on the datapath. Also, as packets would never come to the else branch in ping_lookup(), remove pr_err() from ping_lookup(). Fixes: 35a79e64de29 ("ping: fix the dif and sdif check in ping_lookup") Reported-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Xin Long <lucien.xin@gmail.com> Link: https://lore.kernel.org/r/1ef3f2fcd31bd681a193b1fcf235eee1603819bd.1645674068.git.lucien.xin@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
