iommu/vt-d: Fix compile error [-Werror=implicit-function-declaration]

Browse source

trace_qi_submit() could be used when interrupt remapping is supported,
but DMA remapping is not. In this case, the following compile error
occurs.

../drivers/iommu/intel/dmar.c: In function 'qi_submit_sync':
../drivers/iommu/intel/dmar.c:1311:3: error: implicit declaration of function 'trace_qi_submit';
  did you mean 'ftrace_nmi_exit'? [-Werror=implicit-function-declaration]
   trace_qi_submit(iommu, desc[i].qw0, desc[i].qw1,
   ^~~~~~~~~~~~~~~
   ftrace_nmi_exit
