ethtool: rss: fix indir_table and hkey leak on get_rxfh failure

rss_prepare_get() allocates the indirection table and hash key buffer
via rss_get_data_alloc(), then calls ops->get_rxfh() to populate them.
If get_rxfh() fails, the function returns an error without freeing
the allocation.

Fixes: 4f038a6a02d2 ("net: ethtool: Don't call .cleanup_data when prepare_data fails")
