When an error happens during alias parsing currently the complete
parsing of all attributes of the PMU is stopped. This is breaks old perf
on a newer kernel that may have not-yet-know alias attributes (such as
.scale or .per-pkg).
Continue when some attribute is unparseable.
This is IMHO a stable candidate and should be backported to older
versions to avoid problems with newer kernels.
v2: Print warnings when something goes wrong.
v3: Change warning to debug output
