LU-4017 quota: add setting/getting project id function

Extend Attr RPC to support project ID attribute, new
ioctl is introduced to get/set project id, it is kept
same ioctl number as VFS, you could use:

lsattr -p <file>
chattr -p <file>

Redefine LL_MAXQUOTAS as 3, change
@qsd_acct_failed into qqi, otherwise osd-zfs
could not use USR/GRP quota normally.

Remove osd_quota_migration(), it only output
some messages in case upgrading from 1.8 which
give us extra efforts for project quota, remove
it indead.

also fix a typo bug in osp_attr_set().
