nfs: return negative error value from nfs{,4}_stat_to_errno

Browse Source 
All use sites for nfs{,4}_stat_to_errno negate their return value.
It's more efficient to return a negative error from the stat_to_errno convertors
rather than negating its return value everywhere. This also produces slightly
smaller code.
