Subject: net/mlx5: E-switch, Fix printing wrong error value
Patch-mainline: v5.7-rc5
Git-commit: e9864539053ae15c2d6475833f62d7383f9271ce
References: jsc#SLE-15172

When mlx5_modify_header_alloc() fails, instead of printing the error
value returned, current error log prints 0.

Fix by printing correct error value returned by
mlx5_modify_header_alloc().

Fixes: 6724e66b90ee ("net/mlx5: E-Switch, Get reg_c1 value on miss")
