scsi: qedi: Fix truncation of CHAP name and secret

Browse source

[ Upstream commit 1683ce57f5 ]

The data in NVRAM is not guaranteed to be NUL terminated.  Since
snprintf expects byte-stream to accommodate null byte, the CHAP secret
is truncated.  Use sprintf instead of snprintf to fix the truncation of
CHAP name and secret.
