most: core: Drop device reference after usage in get_channel()
commit b47b493d6387ae437098112936f32be27f73516c upstream.
In get_channel(), the reference obtained by bus_find_device_by_name()
was dropped via put_device() before accessing the device's driver data
Move put_device() after usage to avoid potential issues.
