ArmPlatformPkg/PlatformIntelBdsLib: fix and clean up error handling
InitializeConsolePipe () shadowed its own Status variable, and then
clobbered the top one before printing its error message. Instead,
use a NULL check on the LocateProtocol () output argument.
Also clean up coding style on the error path.
