Set last allocated object to the object after the one just allocated
before ORing in the extra top bits. Also handle the case where this
wraps around.

Don't overrun fname[] array when decoding device flags.
This was spotted by the Coverity checker (CID 1642).

struct mlx4_priv.doorbell_lock is never used, so delete it.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because
these adapters can also be used as ethernet NICs and Fibre Channel
HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the
InfiniBand midlayer.
