mm/kasan: switch from strlcpy to strscpy 

strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value).  strscpy is relatively better as it
also avoids scanning the whole source string.
