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)
    backtrace:

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.

CWE-401 Missing Release of Memory after Effective Lifetime

The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
