removed flaky test

This test was flaky since the potrf function in LAPACK doesn't actually check whether the passed matrix is Hermitian and of full rank, and the test previously passed/failed depending on random initialization.
Used double to hold the 'p' for bernoulli() and geometric() instead of 'real'.

torch.renorm
changed precison threshold for conv3 test

The previous threshold was insufficient and the test occasionally failed. I ran it a large number of times and the actual error reached ~ 3x1e-10, so I propose 4*1e-10 as the new safer threshold.
