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

In the Linux kernel, the following vulnerability has been resolved:

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.
