net: hibmcge: remove unnecessary check for np_link_fail in scenarios without phy.

hibmcge driver uses fixed_phy to configure scenarios without PHY,
where the driver is always in a linked state. However,
there might be no link in hardware, so the np_link error
is detected in hbg_hw_adjust_link(), which can cause abnormal logs.

Therefore, in scenarios without a PHY, the driver no longer
checks the np_link status.
