Exists in master and in 7 other branches imx_3.0.35_4.1.0, imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga, smarc-l5.0.0_1.0.0-ga

ext4: symlink must be handled via filesystem specific operation 

generic setattr implementation is no longer responsible for
quota transfer so synlinks must be handled via ext4_setattr.
