[ Upstream commit fef31ecaaf2c5c54db85b35e893bf8abec96b93f ]

Current compilation produces the following warnings:

tools/pci/pcitest.c: In function 'run_test':
tools/pci/pcitest.c:56:9: warning: unused variable 'time'
[-Wunused-variable]
double time;
^~~~
tools/pci/pcitest.c:55:25: warning: unused variable 'end'
[-Wunused-variable]
struct timespec start, end;
^~~
tools/pci/pcitest.c:55:18: warning: unused variable 'start'
[-Wunused-variable]
struct timespec start, end;
^~~~~
tools/pci/pcitest.c:146:1: warning: control reaches end of non-void
function [-Wreturn-type]
}
^

Fix them:
- remove unused variables
- change function return from int to void, since it's not used
