Add an ERR_CAST() macro to complement ERR_PTR and co. for the purposes of
casting an error entyped as one pointer type to an error of another pointer
type whilst making it explicit as to what is going on.
This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct.

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