scsi_proc: make proc_scsi_host_open() preallocate a bigger buffer
Some of the ->show_info() instances really spew a lot; it's not a problem wrt correctness (seq_read() will grow buffer and call the sucker again), but in this case it makes sense to start with a somewhat bigger one - they often do exceed one page worth of output.
