mailbox: mailbox-test: free channels on probe error

In the Linux kernel, the following vulnerability has been resolved:

prevents a leak, but also UAF scenarios because the client structure
will be removed nonetheless because it was allocated with devm.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
