common/body_detection: Update reset code to prevent extra state changes
`body_detect_reset` calls `body_detect_change_state` even if there is
no actual state change. When host notifications are enabled this can
cause extraneous events that result in incorrect motion sensor
timestamps as the motion sense task uses the time of the last MKBP
event to update timestamps in the FIFO.
