Fixes a memory leak related to task dependencies as there was no call to free resources from implicit tasks
Segfault at the fery first line of kmp_dephash_free_entries() while trying to dereference a pointer passed as a parameter. The pointer to memory allocated by kmp_fast_allocate() became invalid after __kmp_free_fast_memory() was called.
See comment below (line 5757)
Calling this after __kmp_free_fast_memory( thread ); was called in line 5704 causes crash on sparselu_taskdep benchmark from kastors suite.
