[Intel-gfx] [patch] drm/i915/gvt: cleanup a type issue in submit_context()

[Dan Carpenter]

submit_context() should return negative error codes and zero on success
but by mistake we made it a bool.  I've changed it to int.  Also I made
it static because this isn't referenced in any other files.

This doesn't affect runtime because the return is eventually propogated
to elsp_mmio_write() where it is ignored.
