Subject: [PATCH] net/mlx4: fix crash when configure is not called

Although uncommon, applications may destroy a device immediately after
probing it without going through dev_configure() first.

This patch addresses a crash which occurs when mlx4_dev_close() calls
mlx4_mr_release() due to an uninitialized entry in the private structure.

And the device's B-tree should be allocated once.

Fixes: 9797bfcce1c9 ("net/mlx4: add new memory region support")
