perf tools: Fix endian conversion reading event attr from file header
commit eda3913bb70ecebac13adccffe1e7f96e93cee02 upstream.
The perf_event_attr struct has two __u32's at the top and
they need to be swapped individually.
With this change I was able to analyze a perf.data collected in a
32-bit PPC VM on an x86 system. I tested both 32-bit and 64-bit
binaries for the Intel analysis side; both read the PPC perf.data
file correctly.
-v2:
- changed the existing perf_event__attr_swap() to swap only elements
of perf_event_attr and exported it for use in swapping the
attributes in the file header
- updated swap_ops used for processing events
