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'.
