[ Upstream commit 65e5d27df61283e5390f04b09dc79cd832f95607 ]

If aq_nic_stop() fails, aq_ndev_close() returns err without calling
aq_nic_deinit() to release the relevant memory and resource, which
will lead to a memory leak.

We can fix it by deleting the if condition judgment and goto statement to
call aq_nic_deinit() directly after aq_nic_stop() to fix the memory leak.
