Subject: net/mlx5: Increase number of max QPs in default profile

From: Maor Gottlieb <maorg@mellanox.com>


[ Upstream commit 5f40b4ed975c26016cf41953b7510fe90718e21c ]

With ConnectX-4 sharing SRQs from the same space as QPs, we hit a
limit preventing some applications to allocate needed QPs amount.
Double the size to 256K.
