[PATCH v3] common/sfc_efx/base: set return code in case of the error

[Artemii Morozov]

If the prefix for the rss hash was not chosen the
ENOTSUP error should be returned. Before this patch
the zero code was returned in case of an error.

Fixes: f784cdc5cbb1 ("common/sfc_efx/base: provide control to deliver RSS hash")
