[dpdk-dev] [PATCH] net/mlx4: use anonymous DV allocator argument

[Michael Baum <michaelba@mellanox.com>]

The mlx4_pci_probe function defines an struct mlx4dv_ctx_allocators type
variable several hundred rows after it starts, with the only use it
being passed as a parameter to the mlx4_glue->dv_set_context_attr
function.
However, according to DPDK Coding Style Guidelines, variables should be
declared at the start of a block of code rather than in the middle.
Therefore, to improve the Coding Style, the variable is passed directly
to the function without declaring it before.
