common/mlx5: remove useless assignment

The mlx5_dev_to_pci_addr function defines a variable called ret inside a
loop and uses it.

During the loop, the function assigns a value within the variable and
breaks from the loop, so that this assigning has done nothing and is
actually unnecessary.

Remove the unnecessary assigning.

net/mlx5: fix host physical function representor naming

The new kernel adds the names like "pf0" for Host PCI physical
function representor on Bluefield SmartNIC hosts. This patch
provides correct HPF representor recognition over the kernel
versions 5.7 and laters.

The following port naming formats are supported:

- missing physical port name (no sysfs/netlink key) at all,
master is assumed

- decimal digits (for example "12"), representor is
assumed, the value is the index of attached VF

- "p" followed by decimal digits, for example "p2", master
is assumed

- "pf" followed by PF index, for example "pf0", Host PF
representor is assumed on SmartNIC systems.

- "pf" followed by PF index concatenated with "vf" followed by
VF index, for example "pf0vf1", representor is assumed.
If index of VF is "-1" it is a special case of Host PF
representor, this representor must be indexed in devargs
as 65535, for example representor=[0-3,65535] will
allow representors for VF0, VF1, VF2, VF3 and for host PF.

common/mlx5: share kernel interface name getter

Some configuration of the mlx5 port are done by the kernel net device
associated to the IB device represents the PCI device.

The DPDK mlx5 driver uses Linux system calls, for example ioctl, in
order to configure per port configurations requested by the DPDK user.

One of the basic knowledges required to access the correct kernel net
device is its name.

Move function to get interface name from IB device path to the common
library.
