package/qemu: bump to hot-fix release 3.1.1.1

Fixes a couple of important things and among other things the build of
pvrdma code:

----------------------->8---------------------
  In function 'create_qp':
  hw/rdma/vmw/pvrdma_cmd.c:517:16: error: 'rc' undeclared
----------------------->8---------------------

Bumped into this build problem while building vanilla
qemu_arm_versatile_defconfig.
