[PATCH] PCI: vmd: Fix two issues reported by Smatch

[korantwork]

From: Xinghui Li <korantli@xxxxxxxxxxx>

There is one uninitialized symbol error reported by smatch:
"drivers/pci/controller/vmd.c:931 vmd_enable_domain()
error: uninitialized symbol 'ret'."

Fix it by assigning ret with pci_reset_bus return.

And one inconsistent indenting warning:
"drivers/pci/controller/vmd.c:1058 vmd_resume()
warn: inconsistent indenting"

Fix it by formating its indenting.

Fixes: 0a584655ef89 ("PCI: vmd: Fix secondary bus reset for Intel bridges")
Fixes: d899aa668498 ("PCI: vmd: Disable MSI remapping after suspend")
