net: smc91x: Fix up type mismatch in smc_drv_resume().

smc_drv_resume() takes a struct device, while smc_enable_device() takes a
platform device. This fixes up the smc_enable_device() callsite with the
proper pointer.

It's not obvious when this change was introduced, as git history doesn't
go back that far. Presumably the resume code has always been broken in
this fashion.
