media: chips-media: wave5: Fix memory leak on codec_info allocation failure

Browse source

[ Upstream commit a519e21e32 ]

In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is
allocated via kzalloc(). If the subsequent allocation for inst->codec_info
fails, the functions return -ENOMEM without freeing the previously
allocated instance, causing a memory leak.

Fix this by calling kfree() on the instance in this error path to ensure
it is properly released.
