[PATCH] net: trivial: fix fsl fec_main mdio write return value

[Albert ARIBAUD (3ADEV)]

If the MDIO enf-of-transfer wait loop does not time out,
0 should be returned to the caller through ret, but ret
was not reset to 0 after receiving the return value of
pm_runtime_get_sync(). Reset ret when no time out occurred.
