Subject: [PATCH v2 net-next] net/mlx5: net/mlx5: Fix some error messages

This code was using IS_ERR() instead of PTR_ERR() so it prints 1 instead
of the correct error code.  Even better would be to use %pe which prints
out the name of the error, as in "ENOMEM", "EINVAL" etc.

Fixes: 25cb31768042 ("net/mlx5: E-Switch, Improve error messages in term table creation")
Signed-off-by: Dan Carpenter <dan.carpenter@...cle.com>

v2:  Use %pe instead of %ld.

Leon says this goes through netdev instead of the RDMA tree.
