drm/xe/uapi: Fix kernel-doc for DRM_XE_VM_BIND_FLAG_DECOMPRESS

There is kernel-doc warning for DRM_XE_VM_BIND_FLAG_DECOMPRESS:

  ./include/uapi/drm/xe_drm.h:1060: WARNING: Block quote ends without
  a blank line; unexpected unindent.

Fix the warning by adding the missing '%' prefix to
DRM_XE_VM_BIND_FLAG_DECOMPRESS in the kernel-doc list entry for
struct drm_xe_vm_bind_op.
