Jan Kara 25754be3ca udf: Provide saner default for invalid uid / gid
[ Upstream commit 116e5258e4115aca0c64ac0bf40ded3b353ed626 ]

Currently when UDF filesystem is recorded without uid / gid (ids are set
to -1), we will assign INVALID_[UG]ID to vfs inode unless user uses uid=
and gid= mount options. In such case filesystem could not be modified in
any way as VFS refuses to modify files with invalid ids (even by root).
This is confusing to users and not very useful default since such media
mode is generally used for removable media. Use overflow[ug]id instead
so that at least root can modify the filesystem.
