commit ce6a80d1b2f923b1839655a1cda786293feaa085 upstream.
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")
