[PATCH next] irqchip/ls-scfg-msi: Fix NULL dereference in error handling

[Dan Carpenter <dan.carpenter@linaro.org>]

The call to irq_domain_remove(msi_data->parent); was accidentally left
behind during a code refactor.  It's not necessary to free
"msi_data->parent" because it is NULL and, in fact, trying to free it
will lead to a NULL pointer dereference.  Delete the unnecessary code.

Fixes: 94b59d5f567a ("irqchip/ls-scfg-msi: Switch to use msi_create_parent_irq_domain()")
