net/mlx5e: fix double free in macsec_fs_tx_create_crypto_table_groups

Browse source

[ Upstream commit aeb660171b ]

In function macsec_fs_tx_create_crypto_table_groups(), when the ft->g
memory is successfully allocated but the 'in' memory fails to be
allocated, the memory pointed to by ft->g is released once. And in function
macsec_fs_tx_create(), macsec_fs_tx_destroy() is called to release the
memory pointed to by ft->g again. This will cause double free problem.
