xen/pvcalls: fix null pointer dereference on map->sock
[ Upstream commit 68d2059be660944152ba667e43c3b4ec225974bc ]
Currently if map is null then a potential null pointer deference
occurs when calling sock_release on map->sock. I believe the
actual intention was to call sock_release on sock instead. Fix
this.
