dmaengine: acpi: Avoid comparison GSI with Linux vIRQ



stable inclusion
from linux-4.19.208
commit 523559507138ca4abcf4c2522c0061071c1d60a0

--------------------------------

commit 67db87dc upstream.

Currently the CRST parsing relies on the fact that on most of x86 devices
the IRQ mapping is 1:1 with Linux vIRQ. However, it may be not true for
some. Fix this by converting GSI to Linux vIRQ before checking it.
