staging: mt7621-eth: fix return value check in mtk_connect_phy_node()
In case of error, the function of_phy_connect() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
Fixes: e3cbf478f846 ("staging: mt7621-eth: add the drivers core files")
