zpool: remove redundant zpool->type string, const-ify zpool_get_type
Make the return type of zpool_get_type const; the string belongs to the zpool driver and should not be modified. Remove the redundant type field in the struct zpool; it is private to zpool.c and isn't needed since ->driver->type can be used directly. Add comments indicating strings must be null-terminated.
