[PATCH] scsi: proc: use snprintf() for the host name

[shao.mingyin]

From: Shao Mingyin <shao.mingyin@xxxxxxxxxx>

scsi_proc_host_add() and scsi_proc_host_rm() format host_no into a
10-byte buffer with sprintf().  host_no is an unsigned int, and once
it grows past nine digits the %d output plus the terminator no longer
fits; use snprintf().
