remoteproc: sysmon: fix shutdown_acked state
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.
