iget: stop JFFS2 from using iget() and read_inode()

Stop the JFFS2 filesystem from using iget() and read_inode().  Replace
jffs2_read_inode() with jffs2_iget(), and call that instead of iget().
jffs2_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.

jffs2_do_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
