[PATCH] remoteproc: sysmon: fix shutdown_acked state

[Arnd Bergmann]

From: Arnd Bergmann <a...@arndb.de>

The latest version of sysmon_stop() starts by initializing
the sysmon->shutdown_acked variable, but then overwrites it
with an uninitialized variable later:

drivers/remoteproc/qcom_sysmon.c:551:11: error: variable 'acked' is used 
uninitialized whenever 'if' condition is false 
[-Werror,-Wsometimes-uninitialized]
        else if (sysmon->ept)
                 ^~~~~~~~~~~
drivers/remoteproc/qcom_sysmon.c:554:27: note: uninitialized use occurs here
        sysmon->shutdown_acked = acked;
                                 ^~~~~

Remove the local 'acked' variable again and set the state directly.

Fixes: 5c212aaf5457 ("remoteproc: sysmon: Expose the shutdown result")
