IB/usnic: clean up some error handling code

Browse source

This code causes a static checker warning:

	drivers/infiniband/hw/usnic/usnic_uiom.c:476 usnic_uiom_alloc_pd()
	warn: passing zero to 'PTR_ERR'

This code isn't buggy, but iommu_domain_alloc() doesn't return an error
pointer so we can simplify the error handling and silence the static
checker warning.

The static checker warning is to catch place which do:

	if (!ptr)
		return ERR_PTR(ptr);
