fs/affs: use ERR_CAST

Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)).  The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

T x;

T f (...) { <+...
- ERR_PTR(PTR_ERR(x))
+ x

expression x;

- ERR_PTR(PTR_ERR(x))
+ ERR_CAST(x)
