xfrm: Fix memory leak of aead algorithm name
commit 1a6509d99122 ("[IPSEC]: Add support for combined mode algorithms") introduced aead. The function attach_aead kmemdup()s the algorithm name during xfrm_state_construct(). However this memory is never freed. Implementation has since been slightly modified in commit ee5c23176fcc ("xfrm: Clone states properly on migration") without resolving this leak. This patch adds a kfree() call for the aead algorithm name.
