swiotlb-xen: avoid double free

Of the two paths leading to the "error" label in xen_swiotlb_init() one
didn't allocate anything, while the other did already free what was
allocated.

Fixes: b82776005369 ("xen/swiotlb: Use the swiotlb_late_init_with_tbl to init Xen-SWIOTLB late when PV PCI is used")
