Yishai Hadas dd928eae0c RDMA/mlx5: Don't assume that medium blueFlame register exists 
commit 18b0362e87 upstream.

User can leave system without medium BlueFlames registers,
however the code assumed that at least one such register exists.

This patch fixes that assumption.

Fixes: c1be5232d2 ("IB/mlx5: Fix micro UAR allocator")

[bwh: Backported to 3.16:
 - s/bfreg/uuar/g
 - Neither alloc_med_class_uuar() nor num_med_uuar() takes a mlx5_ib_dev
   pointer, so first_med_uuar() doesn't need to take one
 - Adjust context]
