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.
