[PATCH rdma-next v1 2/3] RDMA/core: Use ib_port_state_to_str() for IB state sysfs

[Leon Romanovsky <leon@kernel.org>]

From: Maher Sanalla <msanalla@nvidia.com>

Refactor the IB state sysfs implementation to replace the local array
used for converting IB state to string with the ib_port_state_to_str()
function.
