CVE-2026-98876: host1x: bus: Fix missing ops null check in error teardown

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

host1x: bus: Fix missing ops null check in error teardown

In host1xdeviceinit(), the error teardown paths do not check client->ops before dereferencing it, unlike the forward init paths which correctly guard with 'client->ops &&'. This can result in a NULL pointer dereference if client->ops is NULL.

Fix by adding the missing client->ops check in both the teardown and teardownlate labels.
