am: ignore return value of write_file()

write_file() either returns 0 or dies, so there is no point in checking
its return value.  The callers of the wrappers write_state_text(),
write_state_count() and write_state_bool() consequently already ignore
their return values.  Stop pretending we care and make them void.
