net/mlx5e: Fix uninitialized variable

Browse Source 
There is a potential execution path in which variable *err* is returned
without being properly initialized previously.

Fix this by initializing variable *err* to 0.

Addresses-Coverity-ID: 1472116 ("Uninitialized scalar variable")
Fixes: 0ec13877ce ("net/mlx5e: Gather all XDP pre-requisite checks in a single function")
