smb: avoid pointless cred reference count bump

The creds are allocated via prepare_kernel_cred() which has already
taken a reference.

This also removes a pointless check that gives the impression that
override_creds() can ever be called on a task with current->cred NULL.
That's not possible afaict. Remove the check to not imply that there can
be a dangling pointer in current->cred.
