mtd: ubi: fix unreleased fwnode_handle in find_volume_fwnode()

The 'fw_vols' fwnode_handle initialized via
device_get_named_child_node() requires explicit calls to
fwnode_handle_put() when the variable is no longer required.

Add the missing calls to fwnode_handle_put() before the function
returns.
