raw midi open fails results in verbose message to stdout

[symdeb]

ALSA lib rawmidi_hw.c:384:(snd_rawmidi_hw_open) open /dev/snd/umpC5D0 failed: No such file or directory

It's per design , no regression :)

Though, we may align the behavior with what's done in PCM and others, replace SYSERR() with SYSMSG().

Thank you very much !
