IB/mthca: Fix buddy->num_free allocation size
The num_free field of mthca_buddy has a type of array of unsigned int while it was allocated as an array of pointers. On 64-bit platforms this allocates twice more than required. Fix this by allocating the correct size for the type. This is the same bug just fixed in mlx4 by Eli Cohen <eli@mellanox.co.il>. Signed-off-by: Roland Dreier <roland@purestorage.com>
