[PATCH 5.18 432/879] mt76: mt7921: Fix the error handling path of mt7921_pci_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 4e90db5e21eb3bb272fe47386dc3506755e209e9 ]

In case of error, some resources must be freed, as already done above and
below the devm_kmemdup() and __mt7921e_mcu_drv_pmctrl() calls added in the
commit in Fixes:.
