Subject: [PATCH V2] media: s3c-camif: fix missing disable in tegra_adma_probe().

From: Qiushi Wu <wu000273@....edu>

"pm_runtime_enable()" was not handled by "pm_runtime_disable()"
after a call of the function “pm_runtime_get_sync()” failed.
Thus move the jump target “err_pm” before calling function 
"calling pm_runtime_disable()".

Fixes: babde1c243b2 ("[media] V4L: Add driver for S3C24XX/S3C64XX SoC series camera interface")
Signed-off-by: Qiushi Wu <wu000273@....edu>
