Input: ims-pcu - fix race condition in reset_device sysfs callback
The ims_pcu_reset_device() sysfs callback calls ims_pcu_execute_command()
without acquiring pcu->cmd_mutex. This can lead to data races and
corruption of the shared command buffer if triggered concurrently with
other commands.
Acquire pcu->cmd_mutex before calling ims_pcu_execute_command().
