CIFS: Fix STATUS_CANNOT_DELETE error mapping for SMB2

commit 21496687a79424572f46a84c690d331055f4866f upstream.

The existing mapping causes unlink() call to return error after delete
operation. Changing the mapping to -EACCES makes the client process
the call like CIFS protocol does - reset dos attributes with ATTR_READONLY
flag masked off and retry the operation.
