input: synaptics_i2c_rmi4: Reinitialize list after freeing it



During firmware update and device reset through sysfs, query info
needs to be updated in support_fn_list. However, both these procedures
free the existing list before updation without setting its list head
to consistent state. Reinitialize the list head of support_fn_list
to avoid memory fault during updation.
