rin | sys: Drop redundant NULL check before m_freem(9)
m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c
Compile-tested on amd64/ALL.

1. Protect the nfs request queue with its own mutex
2. make the nfs_receive queue check for signals so that intr mounts
can be interrupted.

manu | Fix soft NFS force unmount
For many reasons, forcibly unmounting a soft NFS mount could hang forever.
Here are the fixes:
- Introduce decents timeouts in operation that awaited NFS server reply.
- On timeout, fails operations on soft mounts with EIO.
- Introduce NFSMNT_DISMNTFORCE to let the filesystem know that a
force unmount is ongoing. This causes timeouts to be reduced and
prevents the NFS client to attempt reconnecting to the NFS server.
Also fix a race condition where some asynchronous I/O could reference
destroyed mount structures. We fix this by awaiting asynchronous I/O
to drain before proceeding.

Get rid of dependency on fs_nfs.h, i.e. source modules with
conditional content depending on if the NFS client is wanted or
not. The server can now be made an independent module not depending
on the nfs client.
Tested with rump_nfs (standalone client), rump_nfsd (standalone
nfsd) and a qemu installation with both the client and the server.

Remove useless and harmful sync(2) call in umount(8)
Remove sync(2) call before unmount(2) in umount(8). This sync(2) is useless
since unmount(2) will perform a VFS_SYNC anyway.
But moreover, this sync(2) may be harmful, as there are some situation where
it cannot return (unreachable NFS server, for instance), causing umount -f
to be uneffective.
