Zilin Guan 38d80307de crypto: starfive - Fix memory leak in starfive_aes_aead_do_one_req() ...

[ Upstream commit ccb679fdae ]

The starfive_aes_aead_do_one_req() function allocates rctx->adata with
kzalloc() but fails to free it if sg_copy_to_buffer() or
starfive_aes_hw_init() fails, which lead to memory leaks.

Since rctx->adata is unconditionally freed after the write_adata
operations, ensure consistent cleanup by freeing the allocation in these
earlier error paths as well.

Compile tested only. Issue found using a prototype static analysis tool
and code review.
