xen: arm: gic-v3: avoid \n in the middle of log messages

These result in log messages such as:

(XEN) d0v0: vGICD: RAZ on reserved register offset 0x00000c
(XEN) d0v0: vGICR: write r2 offset 0x000180
(XEN)  not found<G><3>traps.c:2417:d0v0 HSR=0x93820046 pc=0xffffffc000322bfc gva=0xffffff8000090180 gpa=0x0000008d110180

Fix this by rewording without a \n in the middle. Also add one at the end.
