net/mlx5_core: Add transport domain alloc/dealloc support
Each transport object, namely TIR and TIS, must have a transport domain
number (TDN) identifier.
The driver wrongly assumed that it is OK to use TDN=0 without explicit
TDN allocation from the device.
The TDN will also be used for isolating different processes once user
mode Ethernet will be supported.
