net/mlx5e: fix a double-free in arfs_create_groups

[ Upstream commit 3c6d5189246f590e4e1f167991558bdb72a4738b ]

When `in` allocated by kvzalloc fails, arfs_create_groups will free
ft->g and return an error. However, arfs_create_table, the only caller of
arfs_create_groups, will hold this error and call to
mlx5e_destroy_flow_table, in which the ft->g will be freed again.
