trans-decl.c (gfc_finish_decl): Remove unused second argument 'init'.

Browse Source 
* trans-decl.c (gfc_finish_decl): Remove unused second argument
'init'.  Simplify code accordingly.  Remove calls to
gfc_fatal_error in favor of gcc_assert.
(create_function_arglist): Remove second argument from calls to
gfc_finish-decl.
(gfc_trans_dummy_character): Likewise.
