In qxl_bo_create(), the temporary 'bo' is allocated through kzalloc().
However, it is not deallocated in the following execution if ttm_bo_init()

returning the error.

No.  ttm_bo_init() calls the destroy callback (qxl_ttm_bo_destroy for
qxl) on failure, which will properly cleanup 'bo' and also free it.
