dmaengine: dw-edma: Account for the MSI vector offset
get_cached_msi_msg() returns the base message shared by a multi-MSI
descriptor. dw-edma currently derives per-channel data from its local IRQ
index and does not adjust a common IRQ at all. Both assume eDMA starts at
the descriptor's first vector.
That is not true when eDMA receives a tail subset. Compose each message
from the IRQ offset relative to the descriptor base in both paths.
While at it, avoid reading PCI MSI attributes from descriptors owned by
non-PCI devices.
