[PATCH] _dl_map_object_from_fd: Remove unnecessary debugger notification in error path

[Andreas Schwab <schwab@suse.de>]

After commit ed3ce71f5c ("elf: Move la_activity (LA_ACT_ADD) after
_dl_add_to_namespace_list() (BZ #28062)") it is no longer necessary to
reset the debugger state in the error case, since the debugger
notification only happens after no more errors can occur.
