[PATCH i-g-t 3/5] lib/intel_blt: Use blt_mem_copy() to stress copy functions

[Francois Dugast <francois.dugast@intel.com>]

The new blt_mem_copy() argument ncopies is handed over to the
underlying function blt_bo_copy() which actually runs the copy, so
that the caller of blt_mem_copy() can use a higher level function
to stress the hardware copy function.
