usb: dwc3: meson-g12a: disable clk on error handling path in probe

stable inclusion
from stable-5.10.7
commit 906b0510dde58d0eacad76b1bcb1264bb634f95a
bugzilla: 47429

--------------------------------

commit a5ada3df upstream.

dwc3_meson_g12a_probe() does not invoke clk_bulk_disable_unprepare()
on one error handling path. This patch fixes that.
