PCI: vmd: Fix uninitialized variable usage in vmd_enable_domain()
The ret variable in the vmd_enable_domain() function was used uninitialized when printing a warning message upon failure of the pci_reset_bus() function. Thus, fix the issue by assigning ret with the value returned from pci_reset_bus() before referencing it in the warning message. This was detected by Smatch: drivers/pci/controller/vmd.c:931 vmd_enable_domain() error: uninitialized symbol 'ret'.
