[PATCH] staging: i2o: Remove uses of return value of seq_printf

[Joe Perches]

Even though this subsystem will go away soonish, using
the return value of seq_printf prevents changing the
return type of seq_<foo> functions to void.

This allows seq_<foo> functions to become void functions
without breaking compilation if this subsystem isn't
deleted before the seq_<foo> functions are converted.

Eliminate these uses by changing the return value of
the enclosing i2o_report_query_status function to void.
Nothing uses the return value of this function.

Change one fixed string to seq_puts just to keep the
silly patch checker quiet.
