enetc: Fix unused var build warning for CONFIG_OF

Browse source 
When CONFIG_OF is disabled, there is a harmless warning about
an unused variable:

enetc_pf.c: In function 'enetc_phylink_create':
enetc_pf.c:981:17: error: unused variable 'dev' [-Werror=unused-variable]

Slightly rearrange the code to pass around the of_node as a
function argument, which avoids the problem without hurting
readability.
