accel/amdxdna: Fix potential NULL pointer dereference in context cleanup

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix potential NULL pointer dereference in context cleanup aie_destroy_context() is invoked during error handling in aie2_create_context(). However, aie_destroy_context() assumes that the context's mailbox channel pointer is non-NULL. If mailbox channel creation fails, the pointer remains NULL and calling aie_destroy_context() can lead to a NULL pointer dereference. In aie2_create_context(), replace aie_destroy_context() with a function which request firmware to remove the context created previously.
