[PATCH 2/7] lib/ucs2_string: Avoid WARN in library code

[Ard Biesheuvel <ardb@kernel.org>]

It's not really the job of library code to WARN and potentially bring
down the system (with panic_on_warn=1) on a condition that is really
not something to obsess over.

So drop the WARN_ON_ONCE() from ucs2_strscpy().
