[PATCH 6.3 06/13] nfs: dont report STATX_BTIME in ->getattr

From: Jeff Layton <jlayton@kernel.org>

commit cded49ba366220ae7009d71c5804baa01acfb860 upstream.

NFS doesn't properly support reporting the btime in getattr (yet), but
61a968b4f05e mistakenly added it to the request_mask. This causes statx
for STATX_BTIME to report a zeroed out btime instead of properly
clearing the flag.
