drm/xe/vf: Reset recovery_queued after issuing RESFIX_START

During VF_RESTORE or VF_RESUME, the GuC sends a migration interrupt and
clears the RESFIX_START marker. If migration or resume occurs before the
VF issues its own RESFIX_START, VF KMD may receive two back-to-back
migration interrupts. VF then sends RESFIX_START to indicate the beginning
of fixups and RESFIX_DONE to mark completion. However, the second
RESFIX_START fails because the GuC is already in the RUNNING state.

Clear the recovery_queued flag after sending a RESFIX_START message to
ignore duplicated IRQs seen before we start actual recovery.

This ensures the state is reset only after the fixup process begins,
avoiding redundant work item queuing.
