CVE-2026-53295

mailbox: add sanity check for channel array

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

mailbox: add sanity check for channel array

Fail gracefully if there is no channel array attached to the mailbox
controller. Otherwise the later dereference will cause an OOPS which
might not be seen because mailbox controllers might instantiate very
early. Remove the comment explaining the obvious while here.
