[PATCH AUTOSEL 5.4 023/205] rtw88: fix error handling when setup efuse info

[Sasha Levin]

From: Ping-Ke Shih <pkshih@xxxxxxxxxxx>

[ Upstream commit f4268729eb1eefe23f6746849c1b5626d9030532 ]

Disable efuse if the efuse is enabled when we failed to setup the efuse
information, otherwise the hardware will not turn off.

Fixes: e3037485c68e ("rtw88: new Realtek 802.11ac driver")
