[PATCH] PCI: brcmstb: Add missing if statement

[Alex Dewar]

brcm_pcie_resume() contains a return statement that was presumably
intended to have an "if (ret)" in front of it, otherwise the function
returns prematurely. Fix this.

I don't know if this code was tested or not, but I assume that this bug
means that this driver will not resume properly.
