Theodore Ts'o db374de7c8 ext4: add lockdep annotations for i_data_sem for ea_inode's
commit aff3bea95388299eec63440389b4545c8041b357 upstream.

Treat i_data_sem for ea_inodes as being in their own lockdep class to
avoid lockdep complaints about ext4_setattr's use of inode_lock() on
normal inodes potentially causing lock ordering with i_data_sem on
ea_inodes in ext4_xattr_inode_write().  However, ea_inodes will be
operated on by ext4_setattr(), so this isn't a problem.
