scsi: qedi: Fix a potential buffer overflow

Browse source

Tell snprintf() to store at most 255 characters in the output buffer
instead of 256. This patch avoids that smatch reports the following
warning:

drivers/scsi/qedi/qedi_main.c:891: qedi_get_boot_tgt_info() error: snprintf() is printing too much 256 vs 255
