[PATCH V2 03/14] perf tools: Remove redundant validation from perf_evlist__propagate_maps

[Adrian Hunter <adrian.hunter@intel.com>]

The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen.  Subsequent patches will
call this code in places where errors are not being returned.
Changing those code paths to return this non-existent error is
counter-productive, so just remove it.
