reiserfs: Unpack tails on quota files
commit d5dee5c395062a55236318ac4eec1f4ebb9de6db upstream
Quota files cannot have tails because quota_write and quota_read functions do
not support them. So far when quota files did have tail, we just refused to
turn quotas on it. Sadly this check has been wrong and so there are now plenty
installations where quota files don't have NOTAIL flag set and so now after
fixing the check, they suddently fail to turn quotas on. Since it's easy to
unpack the tail from kernel, do this from reiserfs_quota_on() which solves the
problem and is generally nicer to users anyway.
