platform/x86: x86-android-tablets: Simplify lenovo_yoga_tab2_830_1050_exit()

lenovo_yoga_tab2_830_1050_exit() only gets called after a successful
lenovo_yoga_tab2_830_1050_init() call so there is no need to check
if lenovo_yoga_tab2_830_1050_codec_[dev|pinctrl] are set.

Also change the exit() order to be the exact reverse of init().
