ANDROID: Fix kernelci build-break in printk.c

commit 0820d8e ("ANDROID: logbuf: Add new logbuf vendor hook to support pr_cont()")
added a vendor hook, but broke kernelci builds with
!CONFIG_ANDROID_VENDOR_HOOKS.

The fix is to remove the old "#if defined(CONFIG_ANDROID_VENDOR_HOOKS)"
guard that is now obsolete.
