perf diff: Fix to work with new hists design
The perf diff command is broken since:
perf hists: Threaded addition and sorting of entries
commit 1980c2ebd7020d82c024b8c4046849b38e78e7da
Several places were broken:
- hists data need to be collected into opened sessions instead
of into events
- session's hists data need to be initialized properly when the
session is created
- hist_entry__pcnt_snprintf: the percentage and displacement
buffer preparation must not use 'ret' because it's used
as a pointer to the final buffer
