iget: stop HFSPLUS from using iget() and read_inode()
Stop the HFSPLUS filesystem from using iget() and read_inode(). Replace
hfsplus_read_inode() with hfsplus_iget(), and call that instead of iget().
hfsplus_iget() then uses iget_locked() directly and returns a proper error
code instead of an inode in the event of an error.
hfsplus_fill_super() returns any error incurred when getting the root inode.
