realtek: return correct error value for phy ops
A behavioural change was introduced with commit 758c88b96963 ("realtek:
Whitespace and codestyle cleanup") causing rtl838x_read_phy() and
rtl838x_write_phy() to unconditionally return -ETIMEDOUT. As a result,
probing the device during boot fails:
Error setting up netdev, freeing it again.
rtl838x-eth: probe of 1b00a300.ethernet failed with error -5
Fix the bootloop caused by this regression with kernel 5.15 on rtl838x
devices, by properly returning 0 on success.
Tested on a Netgear GS108T v3, a Netgear GS310TP v1, a Zyxel GS1900-8HP
v1 and an HPE 1920-8G.
