[PATCH] scsi: qla2xxx: replace snprintf with strscpy

[Wang Xiayang]

As commit a86028f8e3ee ("staging: most: sound: replace snprintf
with strscpy") suggested, using snprintf without a format specifier
is potentially risky if a0->vendor_name or a0->vendor_pn mistakenly
contain format specifiers. In addition, as compared in the
implementation, strscpy looks more light-weight than snprintf.

This patch does not incur any functional change.
