Subject: [PATCH net-next] net: dsa: Fix dependencies with HSR

The core DSA framework uses hsr_is_master() which would not resolve to a
valid symbol if HSR is built-into the kernel and DSA is a module.

Fixes: 18596f504a3e ("net: dsa: add support for offloading HSR")
Reported-by: kernel test robot <lkp@...el.com>
Signed-off-by: Florian Fainelli <f.fainelli@...il.com>
