perf annotate: Fix hashmap__new() error checking
The hashmap__new() function never returns NULL, it returns error
pointers. Fix the error checking to match.
Additionally, set src->samples to NULL to prevent any later code from
accidentally using the error pointer.
Fixes: d3e7cad6f36d9e80 ("perf annotate: Add a hashmap for symbol histogram")
