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

isdn: ipacx: Fix set-but-unused variables. 

The variable 'cda2_cr' is set but unused in ctrl_complete().  Just
kill it off.

Keep the cs->readisac() call just in case the register read has side
effects.
