gfs2: Remove duplicate i_nlink check from gfs2_link()
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.
