Input: synaptics-rmi4 - fix possible double free

[ Upstream commit bce1a78423961fce676ac65540a31b6ffd179e6d ]

The RMI4 function structure has been released in rmi_register_function
if error occurs. However, it will be released again in the function
rmi_create_function, which may result in a double-free bug.
