lockd: fix FILE_LOCKING=n build error
lockd/svclock.c is missing a header file <linux/fs.h>.
<linux/fs.h> is missing a definition of locks_release_private()
for the config case of FILE_LOCKING=n, causing a build error:
fs/lockd/svclock.c:330: error: implicit declaration of function 'locks_release_private'
lockd without FILE_LOCKING doesn't make sense, so make LOCKD and LOCKD_V4
depend on FILE_LOCKING, and make NFS depend on FILE_LOCKING.
