PCI: brcmstb: Initialize "tmp" before use

[ Upstream commit ddaff0af653136ee1e0b49116ecf2988c2fc64ca ]

The variable 'tmp' is used multiple times in the brcm_pcie_setup()
function.  One such usage did not initialize 'tmp' to the current value
of the target register.  By luck the mistake does not currently affect
behavior;  regardless 'tmp' is now initialized properly.
