[PATCH net-next v17 12/14] net: ethtool: strset: Remove unnecessary check on genl_info

[Maxime Chevallier]

All call paths coming from genetlink initialize the genl_info structure,
so that command handlers may use them.

Remove an un-needed check for NULL when crafting error messages in the
strset command. This prevents smatch from assuming this pointer may be
NULL, and therefore warn if it's being used without a NULL check.
