uio_hv_generic: Fix a memory leak in error handling paths
commit 3ee098f96b8b6c1a98f7f97915f8873164e6af9d upstream.
If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be
updated and 'hv_uio_cleanup()' in the error handling path will not be
able to free the corresponding buffer.
In such a case, we need to free the buffer explicitly.
Fixes: cdfa835c6e5e ("uio_hv_generic: defer opening vmbus until first use")
