ALSA: ump: Fix -Wformat-truncation warnings
Filling the rawmidi name and substream name can be truncated, and this
leads to spurious compiler warnings due to -Wformat-truncation.
Although the truncation is the expected behavior, it'd be better to
truncate the string within "(...)"
This patch puts the precision specifies to each %s for fitting the
words within the size-limited strings.
