[Bug #20577] Fix freeing symbols when RUBY_FREE_AT_EXIT
Dynamic symbols point to a fstring. When we free the symbol, we hash the fstring to remove it from the table. However, the fstring could have already been freed, which can cause a crash.
This commit changes it to remove the reference to the fstring before freeing the symbol so we can avoid this crash.
