The mlx5_ib driver supports the extended create_cq and create_qp user
verbs. In the current mechanism, a vendor supporting an extended uverb
should set the appropriate bit in the uverbs_ex_cmd_mask field.
Adding the actual support by setting the required bits in order to
support features like completion time-stamping and cross-channel.
Fixes: 972ecb821379 ('IB/mlx5: Add create_cq extended command')
Fixes: ddf9529be19c ('IB/core: Allow setting create flags in QP init
attribute')

There was a proposal [1] that lifts this requirement, however, this
proposal hasn't been accepted yet, and we want to make things to work
for 4.5. Hopefully, this proposal will be reviewed for 4.6.
