diagnostics: Delete config pointer before overwriting it

Delete m_client_data_hooks before it is reassigned in
tree_diagnostics_defaults.  This fixes a small memory leak in the fortran
frontend, which restores the diagnostics configurations to their default
values with a call to tree_diagnostics_defaults at the end of the main parse
hook.

gcc/ChangeLog:

	* tree-diagnostic.cc (tree_diagnostics_defaults): Delete allocated
	pointer before overwriting it.
