[PATCH] drm/vmwgfx: fix asssignment of vmw_bo_p to NULL

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

cppcheck detected an incorrect assignment:

 [drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c:903]: (warning) Assignment
 of function parameter has no effect outside the function. Did you
 forget dereferencing it?

the original assigment didn't do anything, instead *vmw_bo_p should
be set to NULL.
