Ecore: Fix invalid lock count if DEBUG is enabled

With -DDEBUG, we can see an error message, like:
ERR: You are calling _ecore_lock() from outside of the main loop
     threads in lib/ecore/ecore_private at line 306

Looking at the code shows that ecore_lock fails immediately if
thread debugging is enabled, but ecore_unlock does not, so the
value _ecore_main_lock_count could go below 0.

This is not very important as the value is never used.
