[PATCH v5 01/23] clk: starfive: jh7110-sys: Fix memory leak in reset controller register

[Changhuang Liang]

auxiliary_device_init() returns an error before device_initialize() is
called, so the release callback never runs on this path and the rdev
allocated in jh7110_reset_controller_register() is leaked.

Free rdev when auxiliary_device_init() fails.

Fixes: edab7204afe5 ("clk: starfive: Add StarFive JH7110 system clock driver")
