Add default user/group/project quota properties

Browse Source 
This adds default userquota, groupquota, and projectquota properties to
MASTER_NODE_OBJ to make them accessible during zfsvfs_init() (regular
DSL properties require dsl_config_lock, which cannot be safely acquired
in this context). The zfs_fill_zplprops_impl() logic is updated to read
these default properties directly from MASTER_NODE_OBJ.
