Use common report_file_notify_error function

* src/fileio.c (report_file_notify_error): New function.

* src/inotify.c (report_inotify_error): Remove function.
(inotify_callback, symbol_to_inotifymask, Finotify_add_watch)
(Finotify_rm_watch): Use report_file_notify_error.

* src/lisp.h (report_file_notify_error): Declare external function.

* src/w32notify.c (report_w32notify_error): Remove function.
(Fw32notify_add_watch, Fw32notify_rm_watch):
Use report_file_notify_error.
