Herve Codina 8b0e8b33dc irqdomain: Fixed unbalanced fwnode get and put ...

commit 6ce3e98184b625d2870991880bf9586ded7ea7f9 upstream.

fwnode_handle_get(fwnode) is called when a domain is created with fwnode
passed as a function parameter. fwnode_handle_put(domain->fwnode) is called
when the domain is destroyed but during the creation a path exists that
does not set domain->fwnode.

If this path is taken, the fwnode get will never be put.

To avoid the unbalanced get and put, set domain->fwnode unconditionally.

Fixes: d59f6617ee ("genirq: Allow fwnode to carry name information only")
