The pci transport was stopped twice however due to a workaround in the pci disabling code the disable/enable for first msi interrupt was not balanced. This ended up with irqs not being properly re-enabled and the following print out during recovery: ath10k: failed to receive control response completion, polling.. ath10k: Service connect timeout: -110 ath10k: Could not init core: -110 Legacy interrupt mode was unaffected while msi ranged mode would be partially crippled (it would miss fw indication interrupts but otherwise it worked fine). This fixes completely broken fw recovery for a single msi interrupt mode and fixes subsequent fw crash reports for msi range interrupt mode.
