[PATCH] [net] eth: mlx5: fix macsec dependency

From: Arnd Bergmann <arnd@arndb.de>

Configurations with mlx5 built-in but macsec=m fail to link:

x86_64-linux-ld: drivers/infiniband/hw/mlx5/macsec.o: in function `mlx5r_add_gid_macsec_operations':
macsec.c:(.text+0x77d): undefined reference to `macsec_netdev_is_offloaded'
x86_64-linux-ld: drivers/infiniband/hw/mlx5/macsec.o: in function `mlx5r_del_gid_macsec_operations':
macsec.c:(.text+0xe81): undefined reference to `macsec_netdev_is_offloaded'

Fix the dependency so this configuration cannot happen.

First seen on next-20260615, but probably an old bug.

I could not figure out what caused this error to appear, I have not seen
this combination in many years of randconfig builds that look like they
had the bug. My best guess is that there are so many other dependencies
that it is simply very unlikely.
