Subject: blktrace: use inline function for blk_trace_remove() while blktrace is disabled
From: Yu Kuai <yukuai3@xxxxxxxxxx>
commit cbe7cff4a76bc749dd70264ca5cf924e2adf9296 upstream.
If config is disabled, call blk_trace_remove() directly will trigger
build warning, hence use inline function instead, prepare to fix
blktrace debugfs entries leakage.
