Report incorrect documentation

Location of incorrect documentation

cutlass/examples/05_batched_gemm/batched_gemm.cu

Lines 246 to 250 in e1976da

	// Arbitrary problem size
	int const m = 520;
	int const n = 219;
	int const k = 129;
	int const batch_count = 17;

Describe the problems or issues found in the documentation
The comment says "Arbitrary problem size", which is misleading since batch_count here cannot be modified due to the fixed permutation here:

cutlass/examples/05_batched_gemm/batched_gemm.cu

Line 356 in e1976da

std::vector<size_t> permutation = {14, 11, 3, 10, 1, 13, 9, 4, 6, 16, 8, 15, 7, 12, 0, 2, 5};

Steps taken to verify documentation is incorrect
Change batch_count to other values and the compiled program will not be able to pass checks.

Suggested fix for documentation
Change "Arbitrary problem size" to "Arbitrary matrix shape" and add a blank line between k and batch_count to show that batch_count is not arbitrary here.
