Subject: [PATCH] PCI/ERR: Combine pci_channel_io_frozen cases
Git-commit: b5dfbeacf74865a8d62a4f70f501cdc61510f8e0
Patch-mainline: v5.7-rc1
References: git-fixes

pcie_do_recovery() had two "if (state == pci_channel_io_frozen)" cases
right after each other.  Combine them to make this easier to read.  No
functional change intended.
