[PATCH] net/mana: fix dependencies

[Thomas Monjalon]

The reason for not building is updated
to be consistent with other drivers.

The libibverbs was not detected through pkg-config.
The method dependency() needs to be used first.

The support in rdma-core and Linux is not released yet,
so the documentation is updated.
