CVE-2022-50142

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

intel_th: msu: Fix vmalloced buffers

After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's
a chance of DMA buffer getting allocated via vmalloc(), which messes up
the mmapping code:

> RIP: msc_mmap_fault [intel_th_msu]
> Call Trace:
>  <TASK>
>  __do_fault
>  do_fault
...

Fix this by accounting for vmalloc possibility.
