vfio/mlx5: Fix unwind flows in mlx5vf_pci_save/resume_device_data()
[ Upstream commit cb04444c243c001fc27f275e84792ff1c2b96867 ]
Fix unwind flows in mlx5vf_pci_save_device_data() and
mlx5vf_pci_resume_device_data() to avoid freeing the migf pointer at the
'end' label, as this will be handled by fput(migf->filp) through
mlx5vf_release_file().
To ensure mlx5vf_release_file() functions correctly, move the
initialization of migf fields (such as migf->lock) to occur before any
potential unwind flow, as these fields may be accessed within
mlx5vf_release_file().
