Subject: [PATCH] vfio_pci: Add local source directory as include

Commit 7f92891778df ("vfio_pci: Add NVIDIA GV100GL [Tesla V100 SXM2]
subdriver") introduced a trace.h file in the local directory but
missed adding the local include path, resulting in compilation
failures with tracepoints:

In file included from drivers/vfio/pci/trace.h:102,
                 from drivers/vfio/pci/vfio_pci_nvlink2.c:29:
./include/trace/define_trace.h:89:42: fatal error: ./trace.h: No such file or directory
 #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)

Fix this by adjusting the include path.

Fixes: 7f92891778df ("vfio_pci: Add NVIDIA GV100GL [Tesla V100 SXM2] subdriver")

I'd still like to echo my sentiment that this should not be a def_bool.
We hit this error on our internal testing and we couldn't even turn
off the driver until we fixed this.
