ath10k: fix fw crash by moving chip reset after napi disabled

On SMP platform, when continuously running wifi up/down, the napi
poll can be scheduled during chip reset, which will call
ath10k_pci_has_fw_crashed() to check the fw status. But in the reset
period, the value from FW_INDICATOR_ADDRESS register will return
0xdeadbeef, which also be treated as fw crash. Fix the issue by
moving chip reset after napi disabled.
