iget: stop EXT3 from using iget() and read_inode()

Browse Source 
Stop the EXT3 filesystem from using iget() and read_inode().  Replace
ext3_read_inode() with ext3_iget(), and call that instead of iget().
ext3_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.

ext3_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
