[PATCH v2] clk: starfive: jh7110: fix memory leak in jh7110_reset_controller_register() error path

[Guangshuo Li]

jh7110_reset_controller_register() allocates a jh71x0_reset_adev with
kzalloc() before calling auxiliary_device_init().

When auxiliary_device_init() returns an error, the function exits
without freeing rdev. Since the release callback is only expected to
handle cleanup after successful initialization, rdev should be freed
explicitly in this path.

Add the missing kfree(rdev) before returning from the
auxiliary_device_init() error path.
