net: fix endian check warning in etherdevice.h
Sparse builds have been warning for a really long time now
that etherdevice.h has a conversion that is unsafe.
include/linux/etherdevice.h:79:32: warning: restricted __be16 degrades to integer
This code change fixes the issue and generates the exact
same assembly before/after (checked on x86_64)
Fixes: 2c722fe1c821 (etherdevice: Optimize a few is_<foo>_ether_addr functions)
