pinctrl: sunxi: fix regulator leak in sunxi_pmx_request() error path

Browse source

In the error path of sunxi_pmx_request(), the code calls
regulator_put(s_reg->regulator) to release the regulator. However,
s_reg->regulator is only assigned after a successful regulator_enable().
This causes a memory leak: the regulator obtained via regulator_get()
is never properly released when regulator_enable() fails.
