Re: [Intel-wired-lan] [PATCH] fm10k:Fix error handling in the function fm10k_setup_tc

This fixes error handling in the function fm10k_setup_tc to properly
check if the call to the function fm10k_open has failed by returning
a error and if so return immediately to the caller of the function
fm10k_setup_tc to properly signal this non recoverable failure.
