Since commit 28a06215280 (released in 11.2.0) resuming a failed
post-copy migration calls qemuProcessIncomingDefNew with fd == NULL
rather than -1. The function does not expect to be called with NULL file
descriptor and tries to dereference it causing virtqemud on the
destination host to crash.
Fixes: 28a06215280b99708ed8dc2d183f62ba7b34ccf8
