MFC: r346424
Add support for the ModeSetMasked attribute to the NFSv4.1 server.
I do not know of an extant NFSv4.1 client that currently does a Setattr
operation for the ModeSetMasked, but it has been discussed on the linux-nfs
mailing list.
This patch adds support for doing a Setattr of ModeSetMasked, so that it
will work for any future NFSv4.1 client that chooses to do so.
Tested via a hacked FreeBSD NFSv4.1 client.

Replace "vp" with NULL to make the code more readable.
At the time of this nfsv4_sattr() call, "vp == NULL", so this patch doesn't
change the semantics, but I think it makes the code more readable.
It also makes it consistent with the nfsv4_sattr() call a few lines above
this one. Found during code inspection.

Improve sanity checking for the dircount hint argument to
NFSv3's ReaddirPlus and NFSv4's Readdir operations. The code
checked for a zero argument, but did not check for a very large value.
This patch clips dircount at the server's maximum data size.

Fix LORs between vn_start_write() and vn_lock() in the pNFS server.
When coding the pNFS server, I added several vn_start_write() calls done
while the vnode was locked, not realizing I had introduced LORs and
possible deadlock when an exported file system on the MDS is suspended.
This patch fixes this by removing the added vn_start_write() calls and
modifying the code so that the extant vn_start_write() call before the
NFS RPC/operation is done when needed by the pNFS server.
Flags are changed so that LayoutCommit and LayoutReturn now get a
vn_start_write() done for them.
When the pNFS server is enabled, the code now also changes the flags for
Getattr, so that the vn_start_write() is done for Getattr, since it may
need to do a vn_set_extattr(). The nfs_writerpc flag array was made global
to the NFS server and renamed nfsrv_writerpc, which is consistent naming
for globals in the NFS server.
Thanks go to kib@ for reporting that doing vn_start_write() while the vnode is
locked results in a LOR.
This patch only affects the behaviour of the pNFS server.
