Add negative test for test_svm size check (#1802)

Isuue #875 clarified that CL_INVALID_BUFFER_SIZE should be returned if
clCreateBuffer is passed a pointer returned by clSVMAlloc as its
host_ptr and the size of the buffer exceeds the size of the SVM
allocation.

Add a new negative test to ensure CL_INVALID_BUFFER_SIZE is returned
when the size of buffer exceeds the size of the SVM allocation.

Fixes #1701
