dracut: Do not stop installing drivers if one fails

--add-drivers and --filesystems kernel drivers are added via:
instmods -c
The check option makes the function return if one driver could not get installed without trying to install further drivers which is bad.

The user is still informed ($_silent is by default no), but all modules passed to instmods are tried to be loaded, even if one fails.
