pinctrl: stm32: Fix clock reference leak in stm32_pctl_probe()

stm32_pctl_probe() obtains one clock per bank with
of_clk_get_by_name(), but none of the error paths drop those
references: the loop returns directly when a later clock lookup fails,
and both the clk_bulk_prepare_enable() failure and the err_register
path return without calling clk_bulk_put().  clk_bulk_disable_unprepare()
only disables the clocks, it does not release them.

Release the references on these paths; the success path keeps them as
the driver needs them for suspend/resume.
