PCI: Make FLR and AF FLR reset warning messages different
We have same warning message for FLR and AF FLR and users can't know which
type of resets the PCI device is taking when there are pending
transactions. Print different messages for FLR and AF FLR cases.
[bhelgaas: make code structure parallel, add "anyway" to suggest risk]
