pinctrl: at91-pio4: fix domain name assignment

Browse Source 
commit 7bb97e360acdd38b68ad0a1defb89c6e89c85596 upstream.

Since commit d59f6617eef0 ("genirq: Allow fwnode to carry name
information only") an IRQ domain is always given a name during
allocation (e.g. used for the debugfs entry).

Drop the no longer valid name assignment, which would lead to an attempt
to free a string constant when removing the domain on late probe
failures (e.g. probe deferral).

Fixes: d59f6617eef0 ("genirq: Allow fwnode to carry name information only")
