wifi: mt76: mt7921e: fix rmmod crash in driver reload test

In insmod/rmmod stress test, the following crash dump shows up immediately. The problem is caused by missing mt76_dev in mt7921_pci_remove(). We should make sure the drvdata is ready before probe() finished.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
