gfs2: Remove duplicate i_nlink check from gfs2_link()

Browse source

The duplication is:

    struct gfs2_inode *ip = GFS2_I(inode);
    [...]
    error = -ENOENT;
    if (inode->i_nlink == 0)
        goto out_gunlock;
    [...]
    error = -EINVAL;
    if (!ip->i_inode.i_nlink)
        goto out_gunlock;

The second check is removed. ENOENT is the correct error code for
attempts to link a deleted inode (ref: link(2)).

If we support O_TMPFILE in future the check will need to be updated with
an exception for inodes flagged I_LINKABLE so sorting out this
duplication now will make it a slightly cleaner change.
