staging: lustre: Convert "return seq_printf(...)" uses

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

Convert these "return seq_printf(...)" uses to:

	seq_printf(seq, ...);
	return 0;

Done via cocci script:

@@
struct seq_file *seq;
@@

-	return
	\(seq_printf\|seq_puts\|seq_putc\)(seq,
	...);

+	return 0;

With some additional reformatting and typing post conversion.

Miscellanea:

o convert an rc++ use to a bool
o use seq_puts with fixed strings where appropriate
