nfs-utils 2.4.1, moves from "stat" to "statx
with AT_STATX_DONT_SYNC" in parts of the code.
statx is supported in Linux kernel v4.11 and above.
For all older kernels glibc emulates statx, and it
doesn't support AT_STATX_DONT_SYNC and will return
EINVAL.
When server uses nfs-utils 2.4.1 on kernel v4.10
and older, mount.nfs4 would fail with error
"reason given by server: No such file or directory".
Since Linux v4.4 and v4.9 are LTS, its more likely
that people would use above combination.
This issue has been fixed in nfs-utils 2.4.3 and
above. Backporting fix to 2.4.1.
