Subject: [PATCH] nfs: don't report STATX_BTIME in ->getattr

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.

Cc: stable@...r.kernel.org # v6.3+
Fixes: 61a968b4f05e ("nfs: report the inode version in getattr if requested")
