Cleanup sparse warnings from fs/nfs, mainly
due to undeclared functions or missing static
from functions.
This patch does the following:
1) place static on both the nfs_llseek_dir and
nfs_fsync_dir in dir.c as they where earlier
declared static
2) add shared.h, and put declarations of the
init functions into it.
3) use inline to remove DIRECTIO initialisation
support to cleanup the init/exit code paths
