NFS: Remove dead code from nfs_fs_mount()
In fs/nfs/super.c::nfs_fs_mount() we test for a NULL 'data':
...
if (data == NULL || mntfh == NULL)
goto out_free_fh;
...
and then further down in the function we test 'data' again:
...
nfs_fscache_get_super_cookie(
s, data ? data->fscache_uniq : NULL, NULL);
...
this second check is just dead code since there is no way 'data' could
possibly be NULL here.
We also rely on a non-NULL 'data' in more than one location between these
two tests, further proving the point that the second test is bogus.
This patch removes the dead code.
