net:fec: Add fec_enet_deinit()

[ Upstream commit bf0497f5 ]

When fec_probe() fails or fec_drv_remove() needs to release the
fec queue and remove a NAPI context, therefore add a function
corresponding to fec_enet_init() and call fec_enet_deinit() which
does the opposite to release memory and remove a NAPI context.
