scsi: megaraid_sas: Use scnprintf() for avoiding potential buffer overflow
Since snprintf() returns the would-be-output size instead of the actual
output size, the succeeding calls may go beyond the given buffer limit.
Fix it by replacing with scnprintf().
Also corrected the wrongly passed limit size. The remaining buffer size
must be decremented.
