Jeff Layton a13746ed11 filelock: fix potential use-after-free in posix_lock_inode 
[ Upstream commit 1b3ec4f7c03d4b07bad70697d7e2f4088d2cfe92 ]

Light Hsieh reported a KASAN UAF warning in trace_posix_lock_inode().
The request pointer had been changed earlier to point to a lock entry
that was added to the inode's list. However, before the tracepoint could
fire, another task raced in and freed that lock.

Fix this by moving the tracepoint inside the spinlock, which should
ensure that this doesn't happen.

Fixes: 74f6f5912693 ("locks: fix KASAN: use-after-free in trace_event_raw_event_filelock_lock")
