[ Upstream commit 08db2cf577487f5123aebcc2f913e0b8a2c14b43 ]
SA context is allocated at mlx5_fpga_ipsec_create_sa_ctx, however the counterpart mlx5_fpga_ipsec_delete_sa_ctx function nullifies sa_ctx pointer without freeing the memory allocated, hence the memory leak.
Fix by free SA context when the SA is released.
