Two NFSD commits for recent LTS kernels

Hi-

These two upstream commits have Fixes: tags, but should have also been marked "Cc: stable" :

1b3e26a5ccbf ("NFSD: fix decoding in nfs4_xdr_dec_cb_getattr") 4990d098433d ("NFSD: Fix CB_GETATTR status fix")

As far as I can tell, they can be applied to both origin/linux-6.12.y and origin/linux-6.13.y.

Thanks!
