[PATCH] mlx4_core: fix allocation size

[PATCH] mlx4_core: fix allocation size

[Eli Cohen]

The num_free field of mlx4_buddy has a type of array of unsigned int while it
was allocated as an array of pointers. On 64 bit platforms it would allocate
twice more than required. Fix this by allocating the correct size for the type.

Thanks, applied (and I also queued up a fix for the same bug in mthca)
