[RESEND PATCH] scsi: target: Remove unnecessary strscpy() size arguments

[RESEND PATCH] scsi: target: Remove unnecessary strscpy() size arguments

[Thorsten Blum]

If the destination buffer has a fixed length, strscpy() automatically
determines its size using sizeof() when the argument is omitted. This
makes the explicit sizeof() calls unnecessary - remove them.

Remove some unnecessary curly braces.

No functional changes intended.
