Subject: e1000e: add check on e1e_wphy() return value
Patch-mainline: v4.14-rc1
Git-commit: d75372a2daf5dc48207ee9e5592917e893cddb87
References: bsc#1056664 FATE#322185
Check return value from call to e1e_wphy(). This value is being
checked during previous calls to function e1e_wphy() and it seems
a check was missing here.
