PM: hibernate: Remove size arguments when calling strscpy()
The size parameter is optional and strscpy() automatically determines the length of the destination buffer using sizeof() if the argument is omitted. This makes the explicit sizeof() calls unnecessary. Remove them to shorten and simplify the code.
