wifi: ath12k: fix memory leak in ath12k_pci_remove()
Kmemleak reported this error:
unreferenced object 0xffff1c165cec3060 (size 32):
comm "insmod", pid 560, jiffies 4296964570 (age 235.596s)

The firmware memory was allocated in ath12k_pci_probe(), but not
freed in ath12k_pci_remove() in case ATH12K_FLAG_QMI_FAIL bit is
set. So call ath12k_fw_unmap() to free the memory.
