Hyper-V Dynamic Memory and VMBus misc small patches

This pull request contains two small patches to hv-balloon:
the first one replacing alloca() usage with g_malloc0() + g_autofree
and the second one adding additional declaration of a protocol message
struct with an optional field explicitly defined to avoid a Coverity
warning.

Also included is a VMBus patch to print a warning when it is enabled
without the recommended set of Hyper-V features (enlightenments) since
some Windows versions crash at boot in this case.

----------------------------------------------------------------
Maciej S. Szmigiero (3):
      hv-balloon: avoid alloca() usage
      hv-balloon: define dm_hot_add_with_region to avoid Coverity warning
      vmbus: Print a warning when enabled without the recommended set of features
