[PATCH] scsi: target: Remove size arguments when calling strscpy()

[Thorsten Blum <thorsten.blum@linux.dev>]

The size parameter of strscpy() is optional because strscpy() uses
sizeof() to determine the length of the destination buffer if it is not
provided as an argument. Remove it to simplify the code.

Remove some unnecessary curly braces.

No functional changes intended.
