[Feature request][alsactl] Allow -g/--ignore to be used with init command

[GitHub issues - opened]

alsa-project/alsa-utils issue #75 was opened from MichaIng:

It would be great if the `-g`/`--ignore` flag would have an effect on the `init` command as well, so that `alsactl -g init` does not print and exit with an error, if no sound cards have been found.

Since it can be checked for attached sound cards on Linux easily via /proc or sysfs, this is of minor importance, and probably there is a reason why it is as it is. In this case, probably the `--help` output could be extended by this info, which is currently only present in the man page. Reading the `--help` only, one (or at least me) would not guess that this flag is ignored by the `init` command.
