perf ftrace: Fix hashmap__new() error checking
The hashmap__new() function never returns NULL, it returns error
pointers. Fix the error checking to match.
Additionally, set ftrace->profile_hash to NULL on error, and return the
exact error code from hashmap__new().
Fixes: 0f223813edd051a5 ("perf ftrace: Add 'profile' command")
