fs/affs: use ERR_CAST

Browse Source 
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/)

// <smpl>

type T;
T x;
identifier f;

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

expression x;

- ERR_PTR(PTR_ERR(x))
+ ERR_CAST(x)
// </smpl>
