drm/xe: Protect devcoredump access after unbind
While we don't have the full flow protection when devcoredump
is accessed after device unbind. Let's at least for now
protect against null dereference:
[ 422.766508] KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]
[ 423.119584] RIP: 0010:xe_vm_snapshot_free+0x30/0x180 [xe]
While at it, I also fixed a non-standard code-declaration block
on the similar function of xe_guc_submit.
v2: - Use IS_ERR_OR_NULL (Nirmoy)
- Expand to other functions
