Chuck Lever ad3cbbb0c1 NFSD: Clear TIME_DELEG in the suppattr_exclcreat bitmap 
>From RFC 8881:

5.8.1.14. Attribute 75: suppattr_exclcreat

> The bit vector that would set all REQUIRED and RECOMMENDED
> attributes that are supported by the EXCLUSIVE4_1 method of file
> creation via the OPEN operation. The scope of this attribute
> applies to all objects with a matching fsid.

There's nothing in RFC 8881 that states that suppattr_exclcreat is
or is not allowed to contain bits for attributes that are clear in
the reported supported_attrs bitmask. But it doesn't make sense for
an NFS server to indicate that it /doesn't/ implement an attribute,
but then also indicate that clients /are/ allowed to set that
attribute using OPEN(create) with EXCLUSIVE4_1.

The FATTR4_WORD2_TIME_DELEG attributes are also not to be allowed
for OPEN(create) with EXCLUSIVE4_1. It doesn't make sense to set
a delegated timestamp on a new file.

Fixes: 7e13f4f8d2 ("nfsd: handle delegated timestamps in SETATTR")
