md: change bitmap_unplug and others to void functions
bitmap_unplug only ever returns 0, so it may as well be void. Two callers try
to print a message if it returns non-zero, but that message is already printed
by bitmap_file_kick.
write_page returns an error which is not consistently checked. It always
causes BITMAP_WRITE_ERROR to be set on an error, and that can more
conveniently be checked.
When the return of write_page is checked, an error causes bitmap_file_kick to
be called - so move that call into write_page - and protect against recursive
calls into bitmap_file_kick.
bitmap_update_sb returns an error that is never checked.
So make these 'void' and be consistent about checking the bit.
