ALSA: ump: Shut up truncated string warning
commit ed990c07af70d286f5736021c6e25d8df6f2f7b0 upstream.
The recent change for the legacy substream name update brought a
compile warning for some compilers due to the nature of snprintf().
Use scnprintf() to shut up the warning since the truncation is
intentional.
