Haixin Yu 9754353d0a perf pmu arm64: Fix reading the PMU cpu slots in sysfs 
Commit f8ad6018ce ("perf pmu: Remove duplication around
EVENT_SOURCE_DEVICE_PATH") uses sysfs__read_ull() to read a full sysfs
path, which will never succeeds as it already comes with the sysfs mount
point in it, which sysfs__read_ull() will add again.

Fix it by reading the file using filename__read_ull(), that will not add
the sysfs mount point.
