ANDROID: logbuf: Remove if directive for vendor hooks

When CONFIG_TRACEPOINTS or CONFIG_ANDROID_VENDOR_HOOKS is not set, there
is a build error after commit 01f2392e13 ("ANDROID: logbuf: Add new
logbuf vendor hook to support pr_cont()"):

kernel/printk/printk.c:1962:4: error: implicit declaration of function
'trace_android_vh_logbuf_pr_cont'
[-Werror,-Wimplicit-function-declaration]
                        trace_android_vh_logbuf_pr_cont(&r, text_len);
                        ^
1 error generated.

Remove the #if directive so that this code always builds properly, which
is possible after commit ba75b92fef ("ANDROID: simplify vendor hooks
for non-GKI builds").
