net/mlx: fix meson build with custom dependency path

[ upstream commit de38dd8 ]

If rdma-core is not installed in a standard directory of the system,
it is possible to specify the location of the pkgconfig file via
an environment variable:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:~/rdma-core/build/lib/pkgconfig

In this case, the dependency may become mandatory to specify
for the configuration tests (checking dependency symbols or fields).

Some spacing is also fixed around.

Fixes: 8e49376 ("net/mlx4: add external allocator for Verbs object")
Fixes: 1dd7c7e ("net/mlx4: support meson build")
Fixes: 96d7c62 ("net/mlx5: support meson build")
