Additional fix for bug #45613: handle failures from my_hash_insert
Additional fix for bug #45613: handle failures from my_hash_insert

Testing for presence of stuff in a hash inside the function
that's filling in the hash creates chicken-and-egg type of problems.
This results in test suite failures in mysql-pe in debug mode and 
adds bad initialization dependency in 5.1.
Fixed by removing the debug code.
