Subject: [PATCH] Get LFQ item before capturing callstack.

This is to ensure that thread local structures have been properly
initialized (lock-free queue buffers are thread local), as capturing
callstack involves allocating memory from rpmalloc, which must be
initialized in each thread before allocation.
